Calcutta prawn cocktail is a delicious and refreshing appetizer that combines the flavors of succulent prawns with a tangy and spicy dressing. The prawns are marinated in a mixture of lime juice, ginger, garlic, and spices, then cooked until tender. They are then tossed with a creamy dressing made with mayonnaise, ketchup, Worcestershire sauce, and hot sauce. The cocktail is served chilled, garnished with fresh coriander leaves and a squeeze of lime juice. It is the perfect dish to start a meal or to enjoy as a light and flavorful snack.
