Chessy appe/paddu is a popular South Indian snack made with a fermented rice and lentil batter. It is similar to a savory pancake or dumpling and is usually cooked in a special appe pan. The addition of cheese to the batter gives it a rich and gooey texture, making it a favorite among cheese lovers. Chessy appe/paddu is best enjoyed hot with coconut chutney or sambar.
