Sweet rice powder, known as chapssal-garu (찹쌀가루) in Korean, is a fine flour milled from glutinous short-grain rice. This flour is distinct from regular rice flour due to its high starch content, which creates a uniquely chewy, sticky, and slightly sweet texture when cooked. It is the essential ingredient for making traditional Korean rice cakes (tteok), such as the sweet fillings for songpyeon or the chewy base for injeolmi. For a simple use, mix it with hot water to form a dough, which can then be steamed or pan-fried to create delicious homemade snacks. This powder is also naturally gluten-free, making it a versatile alternative in various baking recipes. It is a fundamental staple in any Korean pantry for creating authentic desserts and festive foods.
