Fish finger
Fish fingers, known as fish sticks in American and Canadian English and by translations of that name in most other languages, are a processed food made using a whitefish, such as cod, haddock or pollock, which has been battered or breaded.
They are commonly available in the frozen food section of supermarkets. They can be baked in the oven, grilled, shallow fried, or deep-fried.
