Brown sugar is a type of sugar that has a soft texture and a slightly molasses-like flavor. It is commonly used as a sweetener in baking and cooking. Brown sugar gets its characteristic color and taste from the presence of molasses, which is a byproduct of the sugar refining process. It adds a subtle caramel note to recipes and is often used in desserts, sauces, and marinades. Brown sugar is a popular choice for those seeking a slightly richer and more flavorful alternative to white sugar.
