• Role in Cuisine

By the end of this article, you’ll be a shrimp expert ready to pick the perfect shrimp for any recipe or cooking method!

Shrimp Classification by Size

One of the most common ways to classify shrimp is by their size, Shrimp can range dramatically in size from smaller than 1 inch to the large jumbo shrimp which can be over 8 inches long

Commercial shrimp sizes are usually categorized by a count per pound. The lower the count per pound, the larger the shrimp size. Common shrimp size classifications are:

• Colossal: 10 shrimp or less per pound
• Jumbo: 11-15 shrimp per pound
• Extra Large: 16-20 per pound
• Large: 21-30 per pound
• Medium: 31-40 per pound
• Small: 41-50 per pound
• Miniature: over 50 per pound

Larger shrimp sizes like colossal and jumbo are great for grilling, sautéing, or preparing shrimp cocktail. Smaller shrimp work well in pastas, salads, soups and stir fries where you want the shrimp well incorporated.

Sorting by Shell Color

Shrimp shells can come in a variety of different natural colors based on the species. Some of the most common shrimp shell colors are:

• Pink: The most common color like wild Gulf shrimp. They have a mild, sweet flavor.
• White: Often farm-raised from places like Thailand. Have a firmer texture.
• Brown: Tend to have an earthier, more robust flavor. Great for bold dishes.
• Red: Vibrant cherry red color. Most famously seen in Argentinian red shrimp.
• Black: The black tiger shrimp has a striking black shell. Offers a hearty shrimp flavor.
• Blue: Blue shrimp are a rare delicacy occasionally found in tropical areas.

The shell color is purely cosmetic and does not necessarily affect the shrimp flavor. It’s more of an indicator of species and origin.

Classification by Origin and Habitat

Another way chefs and consumers classify shrimp is by their origin and habitat. This provides insight into the conditions the shrimp were raised in which impacts texture and taste. Common habitat classifications include:

• Saltwater
• Freshwater
• Farm-raised
• Wild-caught

Saltwater shrimp account for over 80% of the shrimp consumed. But freshwater shrimp species do exist in lakes and rivers. The growing conditions affect the shrimps diet and meat content.

Farm-raised shrimp are cultivated in man-made enclosed pond systems. Whereas wild-caught are netted or trapped from open oceans and waterways. Wild shrimp tend to have more unique flavors based on their environment.

Comparing Farm-Raised vs Wild-Caught

The debate between farm-raised vs wild-caught shrimp is ongoing. Here’s a quick comparison of the two methods:

Farm-Raised Shrimp

• Can be raised in inland ponds anywhere
• Provide consistent size and flavor
• Requires less energy to harvest
• Lower risk of contaminants
• Considered less flavorful by some

Wild-Caught Shrimp

• Harvested from natural habitats
• Unique flavors based on diet
• More susceptible to inconsistencies
• Potential for higher contaminant risk
• Perceived as more premium tasting

From a sustainability perspective, U.S. farm-raised shrimp gets high marks for its eco-friendly practices. But tastes vary on the flavor differences.

Nutritional Content

Shrimp offer a number of nutritional benefits as a lean protein source that’s low in calories. Some of the top nutrients found in shrimp include:

• Protein – Provides 18-20 grams per 3 ounce serving. Important for building muscle.

• Selenium – High levels help boost immune system and thyroid function.

• Vitamin B12 – Helps form red blood cells and maintain the nervous system.

• Zinc – Necessary mineral that promotes wound healing and DNA production.

• Antioxidants – Compounds like astaxanthin battle cellular damage and inflammation.

However, shrimp does also contain relatively high levels of cholesterol at around 160 mg per serving. So those with dietary cholesterol restrictions need to be mindful of overindulging.

Best Cooking Methods

Selecting the right cooking method can make a big difference in bringing out the optimal texture and flavors. Here are some top cooking techniques suited for shrimp:

• Grilling – Adds nice char flavor and cooks quickly.

• Sautéing – Fast cooking in a pan while basting in herbs and butter.

• Broiling – Direct overhead high heat works nicely for shrimp.

• Stir frying – Classic quick cooking method for bite-size shrimp.

• Boiling – Submerging the shrimp in simmering water.

• Baking – Roasted shrimp achieves a nice texture contrast.

• Skewering – Thread shrimp on a skewer for quick grilling.

Larger shrimp sizes are best for the grill, sauté pan, or oven roasting. Smaller shrimp work well for boiling, stir-fries, and shrimp cocktails.

Role of Shrimp in Global Cuisine

The final way to classify shrimp is by examining how they fit into national and regional cuisines around the world:

American Cuisine: Shrimp are enjoyed in classic American dishes like shrimp cocktails, shrimp & grits, jambalaya, and seafood boils.

Spanish Cuisine: Shrimp are key to signature Spanish dishes like paella, tapas, and pisto.

Italian Cuisine: Shrimp are used in pasta, risotto, seafood pasta, cioppino, and fritto misto.
