Mushrooms can be transformed into crispy, flavorful delights by using a simple squishing technique. This method, popularized by the Sarno brothers, works best with oyster, maitake, or lion’s mane mushrooms. Even mushroom skeptics may find themselves converted once they experience the rich, satisfying results. By pressing them down with a heavy pan while cooking, excess moisture is removed, creating a golden-brown crust and meaty texture.
