Vada is a popular South Indian snack made from lentil or legume batter that is deep-fried to create a crispy and savory fritter. It is typically enjoyed with chutneys or sambar.
Soak the urad dal in water for about 4-6 hours. Drain the water and grind the dal into a smooth paste using a little water as needed.
Transfer the dal paste to a mixing bowl and add chopped onions, green chilies, curry leaves, grated ginger, and salt. Mix well to combine.
Heat oil in a deep frying pan. Wet your hands with water, take a small portion of the batter, shape it into a flat disc with a hole in the center to form the vada, and carefully slide it into the hot oil.
Fry the vadas on medium heat until they turn golden brown and crispy. Remove from the oil and drain on paper towels to remove excess oil.
Serve the vadas hot with coconut chutney or sambar.
