Fish and chips is a classic British dish that consists of battered fish, usually cod or haddock, and deep-fried chips. The fish is coated in a light and crispy batter, while the chips are thick-cut and perfectly golden. This dish is typically served with mushy peas and tartar sauce. The secret to making the perfect fish and chips lies in the batter, which should be light and airy, and the chips, which should be crispy on the outside and fluffy on the inside.
