Mushroom Appam is a savory and flavorful variation of the traditional appam recipe. Sliced mushrooms are sautéed with onions, garlic, and spices until cooked and then added to the fermented rice batter. The batter is poured into a greased appam pan and cooked until golden brown and crispy. Mushroom Appam has a delicious umami flavor and a soft, fluffy texture. It can be served with tomato chutney or any spicy gravy.
