Brown sugar is a type of sugar that contains molasses, giving it a moist texture and a rich, caramel-like flavor. It is available in light or dark varieties, depending on the molasses content, with dark brown sugar having a stronger flavor.
Brown sugar is commonly used in baking, sauces, and desserts to add depth and warmth to the taste, as well as in savory dishes for a hint of sweetness. Its slightly sticky texture also makes it a popular choice for recipes requiring moisture.
