MUSHROOMS:

  • Shiitake and Button mushrooms may be used after a thorough washing.
  • Oyster mushrooms should be broken apart in several places. Pay careful attention to the base where small red worms can be found. Thoroughly examine all the inner sections. If insects are found, the mushroom must be discarded.
  • Portobello mushrooms should be checked in the following manner:
    1. Remove stem from mushroom cap.
    2. Examine the detached stem for any sign of worms.
    3. Taking hold of the mushroom cap, scoop out the entire brown fan-like under-part of mushroom.
    4. Wash thoroughly.
