Gulf shrimp are generally flavorful and sweet, with slight variations in taste according to the species. Pinks are tender and sweet. Browns are firm, though somewhat bland, and sometimes have a hint of iodine. Whites, the standard against which other shrimp species — domestic and imported — are often measured, are sweet and firm. It can be hard to tell the Gulf species apart. Part of the confusion stems from naming them by colors: white, pink and brown, since a pink can look white, a brown can be gray, etc. Cooked shells of all species are pinkish red. Raw meats are translucent pink to gray. Cooked meats are pearly white with pink and red shadings.
