What Gives Blue Crayfish Their Color?

To understand if blue crayfish are edible, it helps to first look at what makes them blue. Their brilliant sapphire hue is caused by a genetic mutation that results in excessive production of a certain protein.

This protein, called crustacyanin, is normally found in the blood of other crayfish species. But in blue crayfish, large amounts of crustacyanin accumulate in the shell itself. When this protein binds with the carapace, it produces the spectacular blue coloration.

The mutation for excessive crustacyanin is somewhat rare in the wild. But captive breeding has led to the proliferation of vibrantly blue crayfish commonly sold in the pet trade. Their unique look makes them popular pets. But does it also make them good eating? Let’s dig in further.

Are Blue Crayfish Safe To Eat?

The biggest concern around eating blue crayfish is potential toxicity. Like lobsters, crabs, and other shellfish, crayfish can contain toxins if not handled properly. Eating contaminated shellfish can cause paralytic shellfish poisoning, which may be fatal.

However, when well-sourced and properly cooked, blue crayfish are not inherently unsafe to consume. Their meat itself is not toxic, although the hepatopancreas/tamale (digestive gland) should be avoided. Proper handling and preparation is key to reducing risks.

If eating blue crayfish, only purchase them live from a reputable seafood market. Do not eat any that appear dead or sickly. Store live crayfish in a refrigerator until ready to cook. Handle raw crayfish carefully to avoid cross-contamination. Cook thoroughly until opaque and hot throughout.

When precautions are taken, the meat of blue crayfish is no more dangerous to eat than that of their wild-caught relatives. Still, pregnant women, children, elderly, or immunocompromised individuals may want to avoid them. For most people, though, moderate blue crayfish consumption should be low risk.

What Do Blue Crayfish Taste Like?

Flavors can vary somewhat depending on preparation method. But overall, the taste of blue crayfish meat is described as sweet, mild, and lobster-like. Their texture is similar to shrimp or lobster as well – firm and springy when properly cooked.

Blue crayfish offer a more delicate flavor than wild crawfish. They lack the assertive muddiness of their swamp-dwelling cousins. Their small size also enables a higher ratio of flavorful meat compared to shells.

When boiled or steamed, blue crayfish take on the aromas of the poaching liquid. Seasonings and spices used will directly influence their taste. This allows cooks to customize flavors – Cajun crayfish, lemon-pepper crayfish, Old Bay crayfish, and more.

While not as overtly flavorful as wild crayfish, blue crayfish offer a milder taste and tender texture that many find equally appealing. Their striking color also makes them a fun conversation piece at the dinner table as well!

How To Cook Blue Crayfish

When preparing a blue crayfish feast, keep cooking methods simple to highlight their natural sweetness:

• Boiling – Drop live crayfish into a large pot of boiling salted water mixed with citrus juice, spices, and herbs. Cook for 2-3 minutes until bright orange. Drain and cool.

• Steaming – Place live crayfish in a steamer basket over simmering water and cook for 4-5 minutes. Remove immediately and ice to stop cooking.

• Sautéing – Clean cooked crayfish and sauté meat in butter or olive oil with garlic, thyme, Old Bay and lemon.

• Grilling – Split cooked crayfish in half and baste with olive oil, lime juice and Cajun seasoning. Grill 2-3 minutes until hot.
