Suspend the screens over sawhorses or the backs of chairs. Turn the leaves often to ensure even drying. To air dry herbs with seeds, tie the herbs in small bundles and suspend inside a paper bag with holes punched in the sides. Suspend the bag in a dark area with good air circulation. Collect the seeds when they are dry, and store in rigid light-proof containers.
Microwave drying is a quick and easy method to dry small amounts of herbs.
Lay a single layer of clean, dry leaves between dry paper towels and place them in the microwave for 1 to 2 minutes on high power. Drying will vary with the moisture content of the herb and the wattage of the microwave oven. Let the leaves cool. If they are not brittle, reheat for 30 seconds and retest. Repeat as needed.
