Meat Science and Ribs

"Thinkers get headaches. Worriers get ulcers." Meathead

To achieveAmazing Ribs, or any amazing meat for that matter, we need to know what goeson inside the cooker and inside the meat. As meat begins to heat, it undergoes physical and

chemical changes. And that's the magic. This article addresses some of the concepts of meat

science by focusing on ribs, but there are important lessons for all kinds of meat.

Buying meat

There are a few days right after slaughter when rigor mortis makes the meat tough, but that

usually goes away by the time the meat arrives in your market. So usually, the fresher the

better.

Try to avoid frozen of thawed meat. Muscle fibers contain a lot of liquid. Have you noticed

what happens when you thaw frozen meat? All those juices? That's what happens when the

juices form ice crystals which break open meat fibers. More juices escape and there's no way

to get them back in. Moral of the story: Fresh meat

is usually juicier than frozen meat.

White meat or dark

meat?

According to food scientist Harold

McGee in his definitive bookOn Food

and Cooking, meat is muscle fiber made

mostly of water and protein interspersed

with fat for storing energy and

connective tissues made of collagens.

Red meat is made of "slow-twitch"

muscles designed for slow steady

movement and endurance. White meat is

mostly "fast-twitch" muscle, designed for

brief bursts of energy.

Muscle fibers need fat and oxygen for

fuel. The fat comes from fatty acids in

blood, and the oxygen is carried by the

protein hemoglobin in blood. The

hemoglobin hands off the oxygen to a

close cousin, myoglobin, a protein liquid

which travels through the muscle and

passes it to the fibers.

In general, the more exercise a musclegets, and the older the animal, the greater

the need for myoglobin, and the darker

the color of the meat. Red meat holds

moisture better and is more flavorful

than white meat.

White meat contains less myoglobin andfat, and it dries out more easily when

cooking. Farm raised chickens and

turkeys spend most of their lives on the

ground or in coops, and their breasts are

mostly fast-twitch muscles. Modern

chickens and turkeys have been bred for

large breasts because white meat is more

popular in this country (and I for one,

can't understand why). The legs and

thighs of chickens and turkeys get moreexercise standing, walking, and running,

so they have lots of slow-twitch muscles,

more pigment, more fat, and more flavor.

They are slightly more forgiving when

being cooked.

Ducks and geese are designed for flying

and swimming and they get more

exercise, so they have mostly slow-

twitch muscles and red meat.

Small fish swim with quick darting

motions have mostly fast-twitch muscles

and white meat, but tuna swim long

distances with slow steady tail

movements are so they are mostly red

meat.

Modern domestic pigs have been bred to

have less intra-muscular fat for a health

conscious society, and they don't get

much exercise, so they have become "theother white meat".

All this also means that, when you serve

a rare steak, the bright red juices that

come out are not blood. The blood is

drained from the animal when it is killed.

The red juices are myoglobin.

Meat temperatures that

matter

Here's what's going on inside your meat

as it rises in temperature. These temps

are approximate. Other variables come

into play such as the age of the animal,

acidity, salt content, type of heat, etc.

40-140F This is the microbial "danger

zone" in which bacteria grow most

rapidly, doubling in number in as little as

20 minutes.

95110F Fats start to melt. Enzymes

accelerate tenderizing.

120-130F Protein denaturing starts.

Some fluids get milky. Sugars move to

surface.

130-140F Fats begin to render.

130-140F Target temp for medium rare

chops and steaks, the temperature at

which they are at optimum tenderness,

flavor, and juiciness.

140F Collagens begin to contract and

squeeze juice from muscle fibers. Juices

begin to turn clear and bead on the

surface.

150-170F Collagens melt.

155F Most microbes killed.

Here's a good question from a reader:

"Where I live, boiling temperature is

about 203F due to altitude (4670'). Does

the temperature at which collagen melts

also change with altitude? Does high

altitude cooking mean I should bekeeping the smoker temperature at a

different temperature than if I were at sea

level?"

Boiling temp varies with altitude because

the air pressure is different and the

amount of energy to convert liquid water

to gaseous water is less. Air pressure,

however, does not affect melting temps

or combustion temps.

As to cooker temp, 225F is a good

number at sea level because moisture in

the meat will not evaporate much at that

temp because the meat is colder than the

air around it. Since boiling temp is about

9F lower where you are, you could take

the cooker down to 216F to help

preserve moisture.

What causes properly

cooked pork and poultry

to be pink, even if it is not

smoked?

Several factors: Gases in the atmosphere

of an oven can react with hemoglobin in

meat and turn it pink, especially on theouter edges. They occur in all ovens,

especially those that heat by combustion

such as gas, charcoal, or wood. They

even are present in electric ovens. When

grilling or smoking, there are more of

these gases. They more easily penetrate

the thinner skin and fat layers of younger

animals, so age of the animal is also a

factor.

Also, meats with high levels of naturally

occurring compounds such as

myoglobin, hemo-protein, and

cytochrome C are more likely to turn

pink. Nitrites in meat can also cause

pinking. Nitrites are converted from

nitrates in feed and water bymicroorganisms that are in the animal.

The best way to test for doneness of any

meat is to use a food thermometer. Color

is not a reliable guide. Click here for a

buying guide to food thermometers.

Sous-vide:Low & slow gone wild

Low and slow retains moisture and

concentrates flavor, so that's why shee-

shee chefs are cooking with a new

method calledsous-vide. That's French

for "under vacuum" and it means putting

the meat in a vacuum sealed plastic bag

and immersing it in water at about 140F

for as many as 24 hours! The process

also prevents liquids from escaping, and

some chefs add butter or sauce to the bag

to build more flavor. Sous-vide is tricky,and if you do it wrong you die of

botulism. So don't try this at home.

Why is red meat

sometimes bright red on

the outside and dull gray

on the inside?

Fresh cut meat is purplish in color.Oxygen reacts with oxymyoglobin, the

pigments in red meat, to form the bright

red color of meat in the grocery store.

The interior of the meat may be gray or

brown because oxygen has not

penetrated into the muscle. If, however,

all the meat in the package has turned

gray or brown, it may be spoiling.

Read the fine print when you shop. Try to avoid

meat labeled "enhanced", "flavor enhanced", "self-

basting", "basted", "pre-basted", "injected", or

"marinated". They can have 10-15% by weight

salty fluids injected. Why pay so much for salt

water? Worse still, many pumped meats feelmushy to me when cooked. You do not need these

additives if you prep and cook the meat properly.

If you cannot find a butcher who sells unenhanced

meat, ask if he or she can special order it for you.

It helps to learn about meat and how it is

butchered, but this is complicated stuff. The more

you know, the better, but here's the best tip I can

give you: Get to know your butcher. Knowing a good

butcher may be more important than knowing a good

stock broker. That's my favorite butcher at rightwearing an AmazingRibs.com cap,Dario Cecchiniin

his 200-year-old butcher shop in Panzano-in-Chianti

in Italy.

If you shop at a grocery store, the head butcher is

usually on duty early morning through early

afternoon. Stop at the counter and ask for the head

butcher and the assistant. Find out their names. Chat them up. Swap recipes. Tell them about

AmazingRibs.com! Ask them about their favorite cuts and what they think are some of the

best meats they get. Ask about delivery dates. Big grocers get fresh meat every day, but some

don't. Unless you're on the coast, fish is usually not delivered daily and freshness in fish is

more important than any other meat. Then, one day, bring in a slab of ribs you're proud of and

leave it there for them to enjoy with lunch. Show them you've got the goods.

Soon after you meet them, while they still remember you, call ahead with an order so they can

pull the best cuts out for you or cut things specially for you. Don't be in a hurry. Be willing to

pay full price for the best cuts. Even so, my butcher has been known to set aside the pick of

the litter for me even when it is on sale.

Anatomy of a slab of pork ribs

Meat is a complex system of muscle fibers, connective tissues, fat, and fluids.

Muscle fibers. The muscle cells are about the thickness of a human hair and are surrounded

by diaphanous connective tissue that attaches the muscle fibers to each other. Muscle fibers

are mostly protein and water. These fibers are found in bundles surrounded by connective

tissue.

Connective tissues. Connective tissue is mostly a protein called collagen. More connective

tissue creates ligaments and cements the bundles to the bones. It is mostly elastin. As the

animal ages, grows, and exercises, muscle fibers get thicker and tougher. So do the connective

tissues. When you cook, collagen begins to melt at about 160F and turns to a rich liquid,

gelatin. This gives meat a lot of flavor and a wonderful silky texture. What food scientists call

environment, so their muscles are very

different, with very little connective

tissue. That's one of the reasons why it

never gets tough. But it can dry out

because there is not much collagen to

moisturize the fibers. The texture of fishvaries depending on the life it leads.

Flounder, which lives on the bottom, has

delicate flaky flesh, while topredos like

swordfish, have firmer, darker flesh.For

these reasons, and others, fish can spoil

within days of being caught while red

meats keep much longer.

mouthfeel. When cooking tough cuts of meat with lots of connective tissue, like pork ribs and

pork shoulder, it is important to liquefy collagen. The goal is to get ribs to about 180F slowly

so the collagens can melt.

Fat. Scattered among the fibers are fat cells which store energy for the muscles. Meat with

lots of fat amongst the muscle is called marbledbecause it has a striated look similar tomarble. Lean meat, such as loin meat from the back of the pig, is typically about 75% water,

20% protein, and only 3% fat. Rib meat, depending on what part of the rib cage it comes

from, the age of the pig, the size of the pig, the gender of the pig, and how it is trimmed, is

more like 65% water, 20% protein, and 15% fat. Click here for definitions of thedifferent rib

cuts(baby back, spareribs, country ribs, St. Louis cuts).

Fat is crucial to meat texture. Waxy when it is cold, fat does not evaporate when you are

cooking as does water. At about 130-140F fat starts to melt and lubricate the fibers as they

are getting tougher under the heat.

Fat is also the source of much of the flavor in meat. It absorbs and stores the aromaticcompounds in the animal's food. As the animal ages the flavor compounds build up and get

stronger. After the animal is slaughtered, the fat can turn rancid if stored improperly or too

long. So we have a tradeoff. The muscle fibers and connective tissues get tougher as the

animal ages and exercises, while the fat builds flavor. Because we have become health

conscious fat haters, factory farmed pigs have much less fat than pigs bred prior to 1980.

Fluids.It is important to understand that the reddish color in meat and its juices is not blood.

That was pretty much all drained out in the slaughter house. The ruddiness comes from a

pigment called myoglobin.

What happens as you cook

At about 120F, some of the fluids begin to get milky. Enzymes shift into high gear and

tenderize the meat. As the meat gets approaches 140F, cell walls begin to break open and

release liquids. This is what makes meat juicy. Raw meat isn't very juicy because the cell

walls are all intact. After the fibers break down the juices release more easily as you chew.

That's why a rare steak is juicier than raw steak.

At about 140F red meat begins to turn pink as the myoglobin

begins to change. As the temperature rises and the myoglobin

changes, the juices go from pink to clear, and the meat turns tan.Also at about 140F, the heat causes the sheaths around the

muscle cells to shrink rapidly and squeeze out moisture much

like wringing out a wet wash cloth. It can happen suddenly at

high heat, and the meat will rapidly shrink, stiffen, and become

chewier. Juices will bead and pool on the surface. That's why

medium rare steak cooked to about 130F is much juicier than

well-done steak cooked to 160F. This drying process even

happens when meat is boiled. You would think that boiling meat

would keep it moist, but boiled meat can get as dry as cardboard.

Poaching or braising meat by submerging it in liquid below

212F, the boiling point, will not drive off the moisture as rapidly.

As the hot air circulates in an oven (and all covered grills, smokers and outdoor cookers are

ovens), the moisture on the surface runs off and evaporates. The lower the oven temp, the less

evaporation, and the juicier the ribs. Evaporation is not a problem with a big roast like a pork

butt. If the exterior is a bit dry and crusty on apork buttorbrisket, no sweat. The interior is so

far away that the moisture cannot escape. But when it comes to ribs, the secret to moist meat

is to cook it low and slow. But low and slow has benefits for even thick cuts. It seems to allowmore flavor to develop.

Further cooking transforms more of the compounds in the meat. Some of them begin to

escape as enticing aromas. This is no great loss. We smell powerful scents even if some

aromatic compounds are as low as a few parts per billion. These aromas can cause a problem

however. It will attract the neighbors. Ladies, if you want to catch a man, forget the expensive

perfumes and implants and get a smoker!

The melting of collagen really starts to accelerate as the meat hits 160F and it continues

rapidly on up to 180F. By now lean meat like steak or pork loin is well done and beginning

to dry out. On collagen and fat laden cuts such as pork ribs, pork shoulder, or beef brisket,although the muscle fibers are drying and toughening, the collagen that held them together as

bundles begins to turn to liquefy; the meat gets easier to chew and the gelatinous collagens

makes the texture more pleasing.

Meanwhile the fat is softening, rendering, spreading through the meat to lubricate it, and

dripping out. As it softens, fat absorbs the aromas and flavors from spices in the rub,

marinade, or brine if you used them. Most important, the fat absorbs the smoke flavor if you

are using a smoker. If the meat gets too hot, all the fat will render out and rob the meat of

much of their flavor and texture. That's why, if you use a paprika based rub, you've probably

noticed that the drippings are bright orange. They're loaded with the rub.

The Maillard reaction and caramelization. As the surface of meat heats above the 212F

boiling point, it starts to brown, a process called the Maillard reaction, and it develops a

richness and depth of flavor, not to mention crunchy texture, called "Mr. Brown" or "bark" in

barbecue speak. Sugars also begin to caramelize, contributing to the complexity. If you are

cooking ribs for a stew, as in myMexican Ribsrecipe, browning them in the beginning adds

flavor, as it does for any stewed meat.

The moisture thing

As moisture evaporates, the meat begins to shrink. A slab of pork ribs can lose 20% or moreof its weight in cooking due to shrinkage. So we are faced with a problem. To liquefy the

collagen we need to cook the meat to about 180F. But by then it is well past well-done and

the muscle fibers are drying out. As a result, we need to add moisture.

The water pan. I'm a big fan of putting a water pan above the coals. It pumps moisture into

the atmosphere and that helps prevent evaporation from the surface of the meat. Some of the

moisture will even condense on the cooler meat basting it. Water pans also help develop

flavor and the smoke ring as described below.

Steaming. Another method of adding moisture is to cook the meat in very high humidity by

wrapping it in foil with a little water or juice for part of the cook. This keeps moisture from

escaping and some vapors penetrate the meat. This method is called theTexas Crutch. Do it

right, and it works great. A lot of competition cooks use the Texas Crutch.

Saucing. Another method to get moist meat is to serve it with a sauce. But you knew that.

This site has recipes for all the important regional barbecue sauces with which you can

experiment. Just clickhere. Thin sauces penetrate the meat more easily than thick sauces andbring more moisture to the party.

Injecting. Another method is to pump up the meat with moisture prior to cooking. You could

use a hypodermic with flavorful marinade, and that is a great idea for this cuts likepork

shoulderandbeef brisket, but it's not very practical to inject between each rib. A bit tedious,

and the result doesn't taste like pork.

Marinating. You canmarinatemeat. Marinating works well on leaner meats like chicken, but

the fact is that most marinades do not get very far into the ribs because of the fat. You could

marinate for several days, but that will also pull out much of the pork flavor.

Brining. Brining adds a significant amount of moisture, it helps retain moisture during

cooking, contributes noticeable flavor enhancements, and it's relatively quick: One hour for

ribs. Max. It works great, but most of the time I just don't bother. For more on the subject,

click here.

Mopping,basting, spritzing. A popular method is to mop, baste, or spritz the meat with

flavored water, oil, beer, marinade, vinegar, or fruit juices frequently while cooking. This

helps cool the exterior, and it is essential on an open grill that is running higher than 240F

because it can replace evaporated moisture, but it really doesn't help a lot on closed ovens,

and the problems it causes can outweigh the benefits. Muscle fiber and fat do not absorb a lot

of liquid, especially when they are partially cooked. But the real problem is caused by

opening and closing a cooker. This just pours oxygen onto the coals. So you dump heat out of

the smoker when you lift the lid, the temp dives, and then the coals get excited when they see

daylight. When you close the lid, the chamber warms up quickly, and then zooms way beyondthe target temperature. So you close the dampers to starve the fire and the chamber cools and

begins to die. So you open a damper to get it back up, and finally, about the time it is stable,

you need to add more coals or mop again. The result is a constant yo-yoing of temperature.

Mops were invented by cooks working over an open pit where the fire is hot and the meat

needs to be cooled. But they are a bad idea on a closed smoker, especially a charcoal or wood

smoker. The die-hard traditionalists love the game of fiddling with the vents and the meat.

They call it the essence of barbecue. They love barbecue, the verb. But I love barbecue thenoun more, so I skip the mop. Put the meat on, bone side down, close the lid, and go drink a

beer. Just go away. Leave. It. Alone.

The proper temp

The ideal cooking temp for tough cuts with lots of

connective tissue such as pork ribs, pork shoulder, and

beef brisket is about 225F, hot enough to brown the

surface and get a bit of abark, but not so hot that a lot of

moisture evaporates. You can cook at a lower temp, but

it will take longer for the meat to hit 180F and you risk drying out the meat.

At 225F temp it takes about 3-4 hours to cook a slab of baby backs and about 5-6 hours to

cook a slab of St. Louis cut ribs. The precise time is hard to gauge because each slab is

different, and cooking temperatures tend to yo-yo a bit. Another problem is that it is very hard

to measure the temp of a slab or ribs, especially since the temp can vary from edge to middle,surface to center. So I rely on the clock and somedoneness tests. When I think it is done, I try

to back down on the temperature to about 180F and hold it for 30 minutes. This is tricky on

some cookers. But the important thing to remember is thatspeed kills.

Pink is beautiful

Many smoked meats develop a smoke ring, a bright pink color just under the surface. Some

people think the pink color means the meat is raw, but nothing could be further from the truth.

There is a picture of a pork rib with asmoke ringat the top of this page.

Nitrogen dioxide (NO2) is among the compounds formed in the high heat combustion of

wood, charcoal, and even propane. As these compounds land on the surface of meat,

especially cool moist meat from the fridge, some, including nitrogen dioxide, are moved

deeper into the meat as cells lower in the smoke compounds pull them in with a diffusion and

absorption process. The cells are simply seeking equilibrium. The process is the same as when

someone lights a cigar in a room. All the smoke starts out near the cigar, but eventually it

spreads throughout the room as it achieves equilibrium. After a while it penetrates clothes,

furniture, and even food. Because it is water soluble, cigar smoke will get into wet things first,

like your wife's eyes. Before long you and your cigar will be seeking equilibrium in the

garage.

The smoke ring in meat is caused by four things:

1) low temperature cooking,

2) combustion of the wood at high temperatures to form nitrogen dioxide,

3) nitrogen dioxide, and

4) moisture on the surface of the meat to help move the water soluble nitrogen dioxide into

the meat.

When these conditions are met, nitrogen dioxide in wood smoke reacts with the pigment

myoglobin in meat to form nitrites and nitrates. These are the same compounds added to hot

dogs and other cured meats to preserve them and they also give them their pink color.

When smoke roasting, the moist meat absorbs smoke. Less smoke is absorbed as the cooking

continues because the surface of the meat begins to seal and becomes saturated with smoke.

For this reason putting a pan of water in a smoker helps create a smoke ring. In fact some

smokers, called water smokers, have water pans built in.

Most of the smoke flavoring occurs in the first hour or two of cooking so adding wood to the

fire late in the cook doesn't create as much flavor. It also allows moisture to escape. It's better

to just leave the door closed.

A faux smoke ring can also develop without smoke if you cook low 'n' slow. When meat is

cooked fast, the proteins in the muscle and myoglobin denature at the same time and combine

to turn brown. When cooked slowly, the muscle proteins finish denaturing before the naturally

pink myoglobin denatures and so the meat remains pink. You can occasionally see this

phenomenon in braised meat like a beef stew. It may have been cooked for hours in a liquid at

low temps, yet the meat will still be slightly pink inside.

On the other hand, some meats cooked low and slow in a smoky environment in an electricsmoker will not develop a smoke ring. That is partially because the wood smolders at a low

temp in electrics. Experts at cooking in electric smokers will add a charcoal briquet as well as

wood chunks to create the correct atmospheric conditions for a smoke ring.

Are they ready yet?

The only way to know for sure if thick cuts of meat arecooked properlyis with a meat

thermometer. The problem with ribs is that it is hard to get an accurate meat thermometer

reading because the meat is thin, it curves, and touching the bone with the thermometer can

Even so, you need a good oven thermometer. The one that came with your cooker is probably

inadequate. I highly recommend theMaverick ET-73, aMeathead Hot Stuff Awardwinner.

Heat sources

Some purists cook with hardwood only, but more

often than not, that produces meat that is too smoky,

pungent, bitter, and reminiscent of an ashtray. Gas,

electricity, wood pellets, and charcoal are better fuels

for the backyard chef, and you can get the smoke

flavor with wood chips, chunks, pellets, or sawdust.

Charcoal comes in two flavors: briquets and lump.

Lump charcoal produces a bit more smoke, but it

burns hot and fast. I love it for steaks and lamb, but for

ribs, I prefer briquets.

Enough is enough

One of the biggest mistakes we frequently make is

using too much smoke. Too much smoke can make

your meat bitter or taste like an ash tray. Smoke is like salt. You can always add more but you

can't take it out. Do not try to cook with wood. It is too hard to control the temp and the

amount of smoke. When you become an expert, you may be able to cook with wood only, but

at the outset stick to charcoal, propane, or electricity. I cannot give you a precise amount

because each cooker is different and the amount of wood to get the right flavor will depend on

the volume of the cooking chamber, the airflow, leaks, how often you peak, the kind of wood

you use, and of course, your preferences. You will need to experiment, but a good rule of

thumb is start experimenting with about two ounces of wood, regardless of the cut or weight.

For dense, thick cuts of meat such as pork butts for pulled pork or beef brisket, you can

double or triple the amount of smoke. If the results are not smoky enough, you can add more

wood on your next cook.

Smoke cold meat

There is some evidence that meat right out of the fridge absorbs smoke more readily than

warm meat, so add you wood when the cooker gets up to the target temp. Try to get all your

wood on in the first hour.

Keep your lid on

Some folks like to baste the meat and others like to spritz it with apple juice or beer or wine.

Fogeddaboudit. All this does is let hot air and moisture out of the oven and cool down the

surface of the meat. Bad idea. If you're burning charcoal or wood, the rush of oxygen is like

pouring gas on the fire. Worse idea. Keep the lid on your grill until the meat isready.

Remember, if you're lookin', you ain't cookin'.

Sauce late

Sweet sauces can burn if you add them too early in the process and they can prevent the

smoke from penetrating the meat. For the best saucing strategies,click here.

Seek balance

The secret to Amazing Ribs is to achieve balance between flavors. For barbecued ribs, there

should be a distinct pork flavor, a smoke flavor, and a seasoning flavor from a rub or sauce.

Balance is the key in cooking ribs.

Bottom line

Take your time and have the following on hand: a cooker with good heat control, a good

thermometer, a comfy chair, a good book, and a great beer.
