Langostino tails are a type of seafood that resemble tiny lobster tails and have a sweet, delicate flavor similar to lobster or crab. They are not true lobsters, but are more closely related to crabs. Langostino tails are generally more affordable than true lobster, making them a budget-friendly option for meals. They are sold frozen, precooked, and ready to be added to dishes where shrimp or other seafood might be used. Langostino tails can be found at stores like Trader Joes and Costco. They are often used in recipes like Langostino Lobster Rolls, Langostino Ceviche, and Creamy Langostino Salad Bruschetta.
