Do prawn cocktail crisps contain prawns or any shellfish?

Prawn cocktail crisps typically do not contain actual prawns or shellfish. The flavoring in prawn cocktail crisps is usually a combination of various seasonings meant to mimic the taste of a prawn cocktail sauce, such as tomato, onion, garlic, and paprika. The crisps themselves are usually made from potatoes or other starches, and do not contain any actual seafood ingredients.
