Karnataka rice appam is a traditional South Indian dish made from fermented rice batter. It is a soft and fluffy pancake with a slightly tangy flavor. Appam is typically served for breakfast or as a snack with coconut chutney or sambar. The batter is prepared by soaking rice and urad dal, grinding them into a smooth paste, and fermenting overnight. The fermented batter is then cooked in a special appam pan to achieve the perfect texture and taste.
