Wild-caught cold water rock lobster tail (Jasus tristani) from Tristan da Cunha, the world's most remote inhabited island, situated in the frigid South Atlantic Ocean between South Africa, Argentina, and Antarctica. Sold fresh-frozen per pound at the Costco seafood counter.

Tristan lobster tails are widely regarded by chefs and lobster connoisseurs as among the finest in the world. The lobsters thrive in pristine, icy waters and feed primarily on a natural, vegetarian diet, which gives the meat its signature sweet, delicate, and exceptionally clean flavor. The tails are naturally processed by artisan fishermen with no added chemicals or preservatives, resulting in a remarkably clean appearance and consistent quality. Tristan da Cunha's lobster fishery is certified sustainable by the Marine Stewardship Council (MSC) and is considered one of the best-managed wild fisheries on earth, governed under the authority of the United Kingdom. Tristan lobsters are naturally smaller than other species, with tail sizes typically ranging from two to six ounces, offering flexibility for single-serving presentations or multi-tail combination dishes.
