Ingredients
  

Main
  • 6 king oyster mushrooms
  • 2 tablespoons mixed herbs your choice
  • garlic spray

Equipment

  • 1 Food Dehydrator
  • 1 Chef's Knife
  • 1 Cutting Board
  • 1 Mushroom Brush or Damp Cloth For cleaning mushrooms
  • 1 Airtight Container For storage

Method
 

  1. Gently clean the king oyster mushrooms with a dry brush or a damp cloth, avoiding rinsing them under water to prevent them from absorbing excess moisture.
  2. Trim the very ends of the mushroom stems and then slice the mushrooms uniformly into approximately 1/4-inch thick rounds or planks to ensure even drying.
  3. Arrange the sliced mushrooms in a single layer on the trays of your food dehydrator, ensuring there is no overlapping to allow for proper air circulation.
  4. Lightly mist the arranged mushroom slices with garlic spray, ensuring even coverage without oversaturating them.
  5. Evenly sprinkle your chosen mixed herbs over the garlic-sprayed mushroom slices.
  6. Set the food dehydrator to the recommended temperature for mushrooms (typically 125-135°F or 52-57°C) and begin the drying process.
  7. Dehydrate the mushrooms for approximately 7 to 8 hours, or until they are completely dry, brittle, and snap easily when bent.
  8. Once dried, turn off the dehydrator and allow the mushrooms to cool completely to room temperature on the trays.
  9. Transfer the fully cooled and dried king oyster mushrooms into a clean, airtight container or jar for long-term storage in a cool, dark place.

Notes

For optimal dehydration, slice the King Oyster mushrooms uniformly, about 1/4 inch thick, to ensure even drying. Uneven slices can lead to some pieces being too brittle while others remain pliable, increasing the risk of spoilage. Maintain a consistent dehydrator temperature (typically 125-135°F or 52-57°C for mushrooms) and allow sufficient time, around 7-8 hours, until the mushrooms are brittle and snap easily. Ensure they are completely dry before storing in an airtight container to prevent mold. These dehydrated mushrooms offer intense umami; rehydrate them in warm water for 20-30 minutes before adding to soups, stews, or stir-fries.
