Crumble large mushroom slices into smaller pieces with your hands so they are easier to powderize.

Place crumbled mushroom pieces into a high-powered blender, food processor, or spice grinder. Process into a fine powder, working in small batches if needed.

Transfer finished lion’s mane mushroom powder into an airtight container like a glass jar. Label container with contents and date. Store in a cool, dark place.

For maximum freshness and nutrient preservation, use your homemade lion’s mane powder within 2 months. The delicate compounds can degrade over time with improper storage.
