pearl sugar

Pearl sugar, also known as nibs or pearl sanding sugar, is a coarse granulated sweetener composed of large, irregular sucrose crystals formed through a specialized crystallization process. Originally developed in Belgium and Scandinavia, pearl sugar crystals are approximately 2-4 millimeters in diameter—substantially larger than standard granulated sugar. The crystals are formed by layering thin coats of sugar solution around small seed crystals, creating their characteristic pearl-like appearance. Unlike conventional sugar that dissolves during baking, pearl sugar's crystalline structure remains largely intact through heating, providing distinctive textural contrast and visual appeal to finished baked goods.

Pearl sugar is primarily used as a decorative and textural topping in European pastries and baked goods, most famously in Belgian waffles (gaufres), where it caramelizes slightly during cooking to create crunchy pockets of sweetness. It also appears in Swedish and Norwegian spiced buns (kanelbullar, boller), Danish pastries, and various Scandinavian holiday breads. The sugar is sprinkled atop doughs before baking rather than incorporated into the batter, allowing it to maintain its crystalline structure and provide textural contrast against soft crumb. It is occasionally used in cookies, donuts, and artisanal breads where a crunchy, visible sweetness element is desired.
