Shrimp is the best-selling seafood in the U.S., holding that distinction for at least seven years, according to The Shrimp Council, a branch of the National Fisheries Institute. This tiny shellfish is versatile enough to be prepared and used in an immeasurable number of ways including pan-seared, added to pasta, and fried. Shrimp is low in fat and calories and a good source of protein. When purchasing raw shrimp, it's important to know how to properly prepare the shrimp. Part of that is knowing when they are fully cooked!
Look at the color. The tell-tale sign of cooked shrimp is that it has turned from watery-looking and translucent to bright pink and white.
Test the tail by holding the shrimp upside down so that the curled tail is sticking up. Push back on the tail and it will spring right back if it is fully cooked. If it doesn't or does so slowly, it is likely undercooked.
Feel the shrimp. Cooked shrimp will feel firm and plump to the touch, compared to the more mushy state of the flesh.
