Do not rinse mushrooms or soak them in water. Instead, gently clean them with a damp paper towel to remove any dirt. Cook them on high heat. Mushrooms release liquid when they cook. If you keep the temperature lower, the mushrooms will steam in the liquid. Cooking them at a higher heat will help that liquid cook off faster and give your mushrooms the best texture. Add more fat as needed. Mushrooms are very absorbent; if you think your mushrooms are starting to look a little dry and they will burn, add a little bit more oil or butter to the pan as needed. Do not overcrowd the mushrooms. When mushrooms cook, they need space to let the liquid evaporate. Do not constantly stir mushrooms. When the mushrooms cook, their liquid evaporates, and then gently flipping will help get that golden color and enhance the flavor of the mushrooms.
