Prepare your oven or food dehydrator. Basil leaves dry beautifully in either an oven set to very low heat or a food dehydrator. If you're using the oven, set it to the lowest temperature - 200 Â°F (93 Â°C) or lower. If you're using a food dehydrator, ready it for operation according to the manufacturer's instructions.
Spread dried mushrooms (or all those snipped stems) in a single layer on a small baking sheet and gently toast them in a 250Â° oven until they are completely dry and crisp, 15 to 20 minutes. Let cool, and then grind to a powder in a clean coffee or spice grinder. Stir the intensely flavorful powder into stocks, soups, sauces or casseroles; knead into bread or pasta dough; season a roast or sprinkle over pizza. You can store the powder in a glass jar in a cool, dark cupboard for up to three months. Drying.
