Baking spread is a substitute for butter that is commonly used in British baking recipes. It is typically composed of bovine fat and other ingredients, and has a lower fat content and more water than butter or margarine. Baking spread is designed for baking because of its ease of use and spreadability, which makes it more applicable for most baking recipes. It is marketed as a healthier option, but the fat content is crucial for baking. Baking spread can be used for baking, but it may cause the baked good to spread out wide and no longer be as risen as when using butter. If you cant find baking spread, you can use margarine, softened butter, cream cheese, or even tofu as a substitute. The difference between American and British spread lies in their composition and usage. American baking spread is typically dairy-free and made from a blend of vegetable oils and fats, while British baking spread is mainly dairy spreads with a lower fat content.
