Onion Chili uthappam is a popular and flavorful South Indian breakfast or snack. It’s a savory pancake, thicker than a dosa, made from a fermented batter of rice and urad dal (black gram). The hallmark of onion uthappam is the generous topping of finely chopped onions, which are cooked right into the batter as the uthappam sizzles on the griddle.
