4. Suggest and explain another two methods of your herb’s sample.

- Microwave heating

Microwave can very efficiently case water to evaporate from your herbs, especially because they are so thin, while leaving flavorful compounds and colorful pigments mostly intact. Herbs that would end up brown or gray and flavorless by the time they're done drying in the oven or through hanging will retain their bright green color and much of their aroma after the minute or so it takes to dry them in the microwave.

-Electrical dehydrator

Another fast, easy, and effective way how to dry herbs is to dry herbs using an electric dehydrator. Temperature and air circulation can be controlled more easily. Preheat the dehydrator between 95 F. (35 C.) to 115 F. (46 C.) or slightly higher for more humid areas. Place herbs in a single layer on dehydrator trays and dry anywhere from one to four hours, checking periodically. Herbs are dry when they crumble, and stems break when bent.
