c. brown sugar

Brown sugar is refined sugarcane or sugar beet juice that has been crystallized with the addition of molasses, a byproduct of the sugar refining process. Distinct from white sugar by its distinctive dark color, moisture content, and caramel-like flavor, brown sugar consists of sucrose crystals coated or blended with molasses. Two primary varieties exist: light brown sugar, which contains less molasses and has a delicate flavor, and dark brown sugar, which contains a higher proportion of molasses and delivers a more pronounced molasses flavor with subtle notes of toffee and caramel.

The production process typically involves either adding molasses back to refined white sugar or retaining molasses during the initial crystallization stage. Brown sugar's hygroscopic nature—its tendency to absorb moisture from the air—requires storage in airtight containers to maintain its soft, clumpy texture.

Brown sugar is essential in baking, particularly for cookies, brownies, cakes, and quick breads where its moisture content produces tender crumbs and complex sweetness. Its molasses content imparts depth to spice cakes, gingerbread, and barbecue sauces. The ingredient features prominently in glazes for ham and other meats, in caramel sauces, and in both light and dark applications—light brown sugar in delicate pastries and oatmeal cookies, dark brown sugar in molasses cookies, pecan pies, and robust sauces. It serves as a foundation in coffee drinks, whipped cream toppings, and can be used as a dry rub for grilled meats. When substituting for white sugar, the recipe's texture and flavor profile typically benefit from the added moisture and molasses notes.
