Cocktail Fish is a delicious and tangy appetizer made with fish fillets marinated in a flavorful mixture of spices, lemon juice, and vinegar. The marinated fish is then coated in a batter made with gram flour (besan) and deep-fried until crispy and golden brown. This dish is perfect for parties or as a starter for a seafood lover's meal. Serve it with mint chutney or ketchup for a burst of flavors.
