Margarine is often sold as a replacement for butter. It was originally developed as a substitute for butter and became popular as a cheaper alternative. Margarine is made from vegetable oils and fats and is designed to have a similar taste and texture to butter. It is often used as a spread for bread, toast, and other baked goods, and it can also be used in cooking and baking recipes as a substitute for butter. Some people choose margarine as an alternative to butter due to dietary preferences or health considerations, such as reducing saturated fat intake.
