Chettinad Appam is a traditional South Indian dish that is made with fermented rice and coconut batter. It is a soft and fluffy pancake-like dish that is typically served for breakfast or as a snack. The batter is made by grinding soaked rice and grated coconut together, then fermenting it overnight. The fermented batter is then cooked on a hot griddle or appam pan until golden and crispy on the edges. Serve these delicious appams with coconut chutney or sambar for a complete meal.
