of cornstarch or tapioca pearls

Cornstarch is a refined carbohydrate extracted from corn kernels (Zea mays), primarily from the endosperm. It is produced by wet-milling corn to separate the starch from protein, fiber, and other components, resulting in a fine, white powder with neutral flavor and high amylose content. The starch granules are odorless and nearly flavorless, making cornstarch a versatile thickening agent valued for its clarity and glossy finish in finished dishes.\n\nTapioca pearls are spherical granules derived from tapioca starch, which is extracted from the cassava root (Manihot esculenta), a tropical tuber native to South America. The starch is processed into small pearls through mechanical forming and drying, creating translucent or opaque spheres that absorb liquid and develop a gelatinous, chewy texture when cooked. Tapioca pearls range in size from small (2-3 mm) to large (8-10 mm) and are neutral in flavor.

Cornstarch functions as a primary thickening agent in gravies, sauces, soups, and desserts, particularly in Asian cuisines where it creates silky, glossy textures. It is used in batters for frying (tempura, General Tso's chicken), as a coating for proteins, and in baking as a component of cake flour and puddings. Cornstarch works through gelatinization when heated with liquid, reaching maximum thickening power around 65°C (150°F).\n\nTapioca pearls are best known as an ingredient in bubble tea (boba tea), where they provide textural contrast and are often sweetened with simple syrup. They are also used in traditional Southeast Asian desserts, puddings, and fruit compotes. Larger pearls are chewy; smaller varieties suit puddings and custards. Both ingredients benefit from neutral flavor profiles that allow other ingredients to shine.
