Dehydrator recipes
Mushroom powder
A concentrated seasoning for cooked dishes made from fully dry mushrooms.
Dry only positively identified cultivated edible mushrooms until brittle with no visible moisture. Cool them completely, grind a small batch and transfer the powder immediately to a dry airtight container.
Powder should be made only from mushrooms that have completed the full drying process with no moist or pliable sections.
Ingredients
- cultivated edible mushrooms 760 g
Preparation
- Choose positively identified cultivated edible mushrooms with no slime, darkening or spoilage.
- Brush soil from the mushrooms, rinse quickly if needed and dry the surface at once.
- Cut the mushrooms evenly; never use unknown wild mushrooms because drying does not neutralise natural toxins.
Drying steps
- Arrange the mushrooms in one layer with gaps for moving air.
- Use the setting in the process card and test a cooled piece rather than relying on time alone.
- When every piece is dry and brittle, cool them completely, grind them and seal the powder immediately.

Temperature

How to check doneness
After cooling, every piece must be brittle with no soft centre or visible moisture. Do not include pliable pieces in powder.
Safety first
Use only positively identified cultivated edible mushrooms. Wild mushrooms can contain toxins that drying or grinding does not destroy.
Cooling and storage
Cooling
Keep the powder in a dry airtight container in a cool, dry and dark place. Discard the entire portion if condensation, mould or an unusual smell appears.
Serving ideas
Add small amounts to soups, sauces and stews that will be cooked further.

Frequently asked questions
Why must the mushrooms cool before grinding?
Warm food can create condensation in the container. Cool the dry pieces completely first.
Does drying make wild mushrooms safe?
No. Drying does not neutralise every natural toxin or correct a mistaken identification.
