What is the Difference Between Shrimp and Langoustine? A Detailed Comparison

Seafood lovers often find themselves wondering about the differences between various types of shellfish. Two crustaceans that frequently cause confusion are shrimp and langoustine. Though they appear similar, these shellfish have distinct characteristics that set them apart.

In this article, we’ll explore everything you need to know about shrimp versus langoustine. We’ll cover their physical features, flavors, textures habitats and more. Read on for the complete comparison!

Defining Shrimp
Shrimp are a common type of small shellfish that belong to the suborder Pleocyemata. There are thousands of shrimp species found in freshwater and saltwater environments around the world. Most shrimp are harvested wild, though some types are farmed as well.

The majority of wild shrimp come from Asia, with major producers including Thailand, Vietnam, China, India, and Indonesia The most commonly eaten species are whiteleg shrimp, giant tiger prawn, akiami paste shrimp, and Indian white prawn

In their raw form, shrimp have translucent flesh that ranges from grayish to light pink. Their slender bodies are slightly bent with a segmented shell covering the torso. Shrimp have stalked eyes, long whisker-like antennae, and legs with small claws on two pairs.

When cooked, shrimp flesh becomes opaque and turns a pinkish-orange hue. Their tails curl into a tight C shape when properly prepared. Shrimp provide a tender, moist, sweet flavor with subtly briny notes. Their meat has a soft, flaky texture.

Defining Langoustine

Langoustines are also known as Norway lobsters or Dublin bay prawns. They are a true lobster species within the Nephropidae family. Langoustines reside in rocky seabeds and mud patches of the northeastern Atlantic Ocean and Mediterranean Sea.

The two main langoustine fisheries are located off the coasts of Scotland and Ireland. Langoustines grow up to 10 inches long and weigh 5-9 ounces on average. They have a bright orange shell with shades of red bands.

Their slender bodies have a smooth, cylindrical shape compared to the rough, bumpy shells of true lobsters. Langoustines have a pair of equal-length antennae and claws with spiny ridges. The edible tail meat is white, while roe in females lends a bright coral hue.

Langoustine meat has a sweet, rich, lobster-like flavor with a firm, flaky texture. It is considered a delicacy for its tender, juicy qualities that surpass shrimp. The subtle brininess also sets it apart from the milder taste of shrimp.

Key Differences
Now that we’ve covered the basics, let’s zoom in on the key differences between shrimp and langoustines:

• Habitat – Shrimp live in freshwater and saltwater. Langoustines live only in seawater.

• Size – Shrimp are smaller, reaching a maximum length around 8 inches. Langoustines grow up to 10+ inches.

• Color – Raw shrimp are translucent gray/pink. Langoustines have bright orange shells.

• Shape – Shrimp are slightly bent with segmented shells. Langoustines have smooth, cylindrical bodies.

• Legs & Claws – Shrimp have small claws on two pairs of legs. Langoustines have one pair of equal-sized claws.

• Antennae – Langoustines have two long antennae. Shrimp have shorter whisker-like antennae.

• Flavor – Shrimp taste mildly sweet. Langoustines have a sweet, lobster-like richness.

• Texture – Shrimp are tender with a soft flake. Langoustines have firm, moist meat.

• Roe – Female langoustines contain coral roe that lends sweetness. Shrimp roe is not commonly eaten.

How to Purchase and Store
Both shrimp and langoustines are highly perishable. It’s important to source them fresh and use proper storage methods. Here are some tips:

• For shrimp, look for plump bodies that smell like the ocean, not ammonia. Spotty, slimy shells indicate spoilage.

• Choose langoustines with bright orange shells and clear eyes. Grayish shells or milky eyes mean they are past prime condition.

• Store freshly caught seafood on ice immediately after purchasing. Use within 2 days max.

• Frozen shrimp and langoustine tails can last 6-12 months in the freezer. Thaw gently in the refrigerator.

How to Prepare
You can prepare shrimp and langoustines using similar cooking methods including boiling, grilling, sautéing, baking, and broiling. Keep these preparation tips in mind:

• For optimal flavor, grill shrimp in the shell and peel after cooking.

• Remove the head and shell of langoustines before cooking to prevent overpowering fishy notes.

• Don’t overcook either one! Cook just until the flesh turns opaque.

• Chill both types after cooking. Serve langoustines chilled with mayo or cocktail sauce.

• Add shrimp to pasta, tacos, stir fries, and soups. Use langoustine in risotto, salads, pasta, and surf and turf.

Which is Better?
The question of shrimp versus langoustine comes down to personal preference. Shrimp offer a more delicate, subtly sweet flavor profile. Their meat has a soft, flaky texture suitable for many dishes.

Langoustines provide a bolder, lobster-like taste and firm, moist flesh. They are pricier than shrimp but worth it for special occasions. There’s no right or wrong – it ultimately depends on your flavor and budget preferences!

The Takeaway
While shrimp and langoustines may look alike at first glance, they have several distinct differences when it comes to biology, harvesting, taste, and texture. Both offer delicious flavor to seafood-based dishes. Shrimp deliver mild brininess at a budget-friendly price point. Langoustines provide rich, sweet meat with a higher price tag.

Hopefully this detailed comparison gave you a better understanding of these two popular shellfish. Whether you opt for shrimp, langoustine, or both, be sure to source them fresh and handle them with care. Now go enjoy these scrumptious crustaceans from the sea!
