Mushroom Appam is a delicious and savory variation of the appam, where finely chopped mushrooms are added to the batter. The mushrooms add a meaty and earthy flavor to the appam, making it more filling and satisfying. The batter is prepared by grinding soaked rice and fenugreek seeds, and then mixing it with finely chopped mushrooms, onions, green chilies, and coriander leaves. The appam is cooked in the traditional appam pan, resulting in a crispy edge and a soft center. It can be served with tomato chutney or any spicy curry.
