Butterscotch sauce is a sweet, rich sauce made primarily from brown sugar, butter, and cream. It has a smooth, velvety texture and a deep caramel flavor, which comes from the melting of the brown sugar. This sauce is often used as a topping for desserts like ice cream, pancakes, and cakes. To make butterscotch sauce, the ingredients are typically heated together until the sugar dissolves and the mixture thickens. It can be served warm or cold and can also be flavored with vanilla or sea salt for added depth. This versatile sauce is a favorite in many kitchens.
