Crustacean

 🦞 Different shells, shared tradition.

A crustacean is a broad culinary and biological term. It is used to describe shellfish with a hard external shell. These include lobsters, crabs, shrimp, prawns, and crayfish 🌊. These creatures belong to a larger group of arthropods. They are characterised by segmented bodies, jointed limbs, and a rigid shell. This shell must be shed as they grow. This process is known as molting 🧬.

In the kitchen, crustaceans are prized for their sweet, delicate flesh and their ability to absorb flavour 🧈🔥. They appear in cuisines around the world. Refined classical dishes include lobster thermidor and bisque. There are also casual preparations like boiled shrimp, crab cakes, and seafood stews. While they share common traits, each type of crustacean offers a distinct texture, flavour, and culinary use.

Crustaceans are found in saltwater, brackish, and freshwater environments. This makes them one of the most diverse and widely consumed seafood groups 🌍. Their perishable nature makes freshness and careful handling essential. Many crustaceans are cooked live or processed quickly after harvest. 🦞 From ocean depths to dinner plates, crustaceans are defined as much by their shells as by their flavour.

A note from the kook’s kitchen

This is where I share the things that don’t always make it onto the site. I include quiet techniques, ingredient stories, and the small details. These details make cooking better over time.
