Alot of folks ask me about mushrooms! They wanna know what they can do to sustain their mushroom supply for later months. Easy.....Read below....
You can freeze mushrooms, but it will take a little extra effort on your part! Do not just throw them in the freezer and hope for the best, instead try following these instructions from cooks.com:
Freezing Raw (Freeze whole, for use within 3 months) :
Choose very fresh mushrooms; wipe with a clean cloth to remove dirt. Place each a little apart on a baking tray and open-freeze as quickly as possible. When mushrooms are frozen, pack into containers, fit on a lid and replace in freezer. Use within 3 months. Use straight from the freezer for pies, casseroles or stews or thaw for about 1 hour and use as required.
Wash raw mushrooms. Add 1/2 teaspoon salt to 1 quart rapidly boiling water. To keep mushrooms white, add 1/2 teaspoon lemon juice to water. Add mushrooms. Let water come to a boil again. Boil mushrooms 3 minutes. Rinse with cold water. Drain thoroughly. Seal in plastic bags. Freeze. Will keep about one year.
Freezing Sauteed Mushrooms:
Saute 1 lb. of mushrooms in butter with salt and pepper, using high heat for 1 or 2 minutes, stirring constantly. Cool, then store in small containers and freeze. Use frozen, or thaw to room temperature about one hour; use for omelettes, sauces or served on toast.
Good luck & good eating!
