A crab stick is a type of food that looks like crab meat, but is not actually made from real crab. It is usually made from a type of white fish called surimi that has been mashed up into a smooth paste.
The surimi paste is then mixed with various ingredients like egg, wheat starch, and flavorings to give it the taste and texture of crab meat. The mixture is then shaped into long sticks or other shapes, which are often dyed orange to resemble real crab meat.
Crab sticks are a popular ingredient in sushi rolls and other seafood dishes because they are cheaper than real crab meat and have a longer shelf life. However, they are not as nutritious as real crab and may contain more additives and preservatives.
So, in summary, crab sticks are a type of imitation crab meat made from a mixture of mashed up fish and other ingredients to resemble the taste and texture of real crab meat. They are often used in sushi and other seafood dishes as a cheaper alternative to real crab meat.
