Mushrooms have a unique structure made of fibers called hyphae, which are around 90% water. This unique structure makes it impossible to overcook them.
When they’re cooked, both the water and the air are forced out of the hyphae, collapsing the air pockets and preventing any water or oil from entering the mushroom.
However, because mushrooms already have enough water, add only ¼ cup of water. You can keep adding water as needed until you reach your desired doneness.
