Appam with coconut water is a traditional South Indian dish made from fermented rice batter and coconut water. The batter is prepared by soaking rice and fenugreek seeds overnight, then grinding it with coconut water to a smooth consistency. The batter is left to ferment for a few hours, which gives the appam its signature light and fluffy texture. The appam is cooked in a special appam pan, which gives it a crispy edge and a soft center. It is typically served with coconut milk or chutney for a delicious and nutritious breakfast or snack.
