Badaa piaji, also known as twice fried onion fritters, is a popular street food from Odisha, India. These fritters are made by deep frying a batter made with onions, gram flour, and spices. The first frying makes them crispy on the outside, while the second frying ensures they are cooked through and have a golden brown color. Badaa piaji is often served with chutney or ketchup and is enjoyed as a snack or appetizer.
