Pearl sugar is a type of sugar that comes in small, round granules. It is often used as a topping for baked goods, such as Belgian waffles and brioche, because it doesn't melt during baking. This gives pastries a delightful crunch and a sweet finish. Unlike regular granulated sugar, pearl sugar is larger and has a unique texture. It is commonly found in European baking, particularly in Scandinavian recipes. Pearl sugar adds both visual appeal and a satisfying crunch to desserts, making it a popular choice among bakers.
