Prawns in Garlic Sauce (Langostinos Gran Meson)

Langostinos are not langoustes (spiny lobsters) despite a similar name (in Spanish, lobster is called langosta). Also, langostinos are sometimes confused with Norwegian lobsters called langoustines. Langostinos are actually prawns which, in turn, are basically extra-large shrimp (shrimp are gambas in Spanish). Eat them bathed in the garlicky lemon sauce they are often served swimming in, known in Spain as Gran Mason for a special treat.

Langostinos Gran Meson- Prawns in Garlic Sauce

In Spain, shrimp are almost always served in their shells, even when sauced. The shells provide the flavor of the sea and keep the meat moist. This dish has the shells removed but do salt the shrimp for 10 minutes before using to bring out its flavor. This dish is easy to make and is equally wonderful for weeknight meals or fancy dinner parties.
