Fish Mixture, specifically made with prawns, is a popular South Indian snack that combines crispy, deep-fried prawns with a flavorful mix of spices, curry leaves, and crunchy elements like peanuts or fried lentils. It is a savory, spicy, and addictive snack often enjoyed with tea or as a side dish. The prawns are marinated, coated in a spiced batter, and fried to perfection, then tossed with aromatic spices and additional crunchy ingredients.
