Herbs - Drying or Freezing

It is possible to freeze or dry the greens from herbs, such as parsley, sage and tarragon, for cooking. Following are tips for preserving herbs.

Most herbs are at peak flavor when flower buds first appear, before they are fully open. Pick herbs in the morning, just after the dew evaporates and before the sun is hot. Discard bruised, soiled, or imperfect leaves and stems. With the leaves on the stems, lightly wash in cool running water. Gently shake to remove excess water. Let them drain on paper towels.

Freezing Herbs

Frozen herbs are usually not suitable for garnish. They become limp when thawed. To freeze herbs:

bulletPlace a few sprigs or leaves in freezer wrap or in an airtight, freezer container.
bulletSpread on a tray or cookie sheet and place in the freezer. When frozen solid, pack into airtight containers.
bulletTo use in soups or stew, dice washed herbs and pack into freezer ice cube trays. Fill the spaces with water. Freeze and pop out cubes and put in airtight containers.

For cooked dishes, use the same proportion as fresh ones.

Drying Herbs

The time it takes in ovens or food dehydrators varies with the herb and appliance used. Herbs are dry when leaves crumble off the stem. Don't crush leaves until using them - they'll lose their flavor more quickly.

Air drying in Virginia is difficult because of the high humidity. Ideal conditions are consistent temperatures above 85° F. and humidity below 60%.

To microwave small amounts, place herbs on a paper towel and cover with a second. Set control on high and dry them 1-3 minutes. Check, and if more time is needed, check every 30 seconds. Pay attention, because paper towels can catch fire if hot spots occur.

To oven dry, spread a layer on a shallow baking pan. The pilot light on a gas oven or the light of an electric oven (with or without minimal heat of 110° - 130° F.) works. Higher temperatures cook herbs. You might use a preheated oven with the oven light on. Stir herbs periodically until thoroughly dry.

Place them in airtight containers or jars with tight-fitting lids. Glass keeps aromas in. Herbs must be completely dry or they mold. Store in a cool, dry, dark area, away from light and heat. Dried herbs keep their flavor and color three months in cupboards and up to one year in refrigerators or freezers. To substitute dried herbs, use a generous ¼ teaspoon ground or 1 teaspoon crumbled dried leaves for every tablespoon of fresh chopped herbs.
