Imitation crab is store-bought seafood sticks or flakes. Just like their name describes, they aren’t crabs per se but are rather a combination of starch and whitefish. Also, if you did not know, the sticks are made with Surimi, a whitefish that is ground them bound with starch to resemble a crab leg. They are mostly sold as sticks that are designed to look like the shape of crab legs, hence their name.
