The primary ingredient in fish and chips is fish, most commonly battered and deep-fried white fish such as cod or haddock. This British dish features the fish served alongside thick-cut fries, known as chips in the UK. The fish is often coated in a light batter made from flour and water, creating a crispy exterior when fried. Fish and chips are typically seasoned with salt and served with a side of malt vinegar or tartar sauce. This dish has deep cultural roots in the UK, dating back to the 19th century, and remains a beloved staple across British society.
