oshiruko

Oshiruko is a traditional Japanese dessert consisting of a hot, sweet red bean soup made from azuki beans and sugar, commonly served with pieces of mochi (glutinous rice cake) or shiratama dango. The texture can vary from smooth, when the beans are mashed and strained, to chunkier, when some whole beans remain in the broth. Variants may use only the liquid or incorporate the whole beans for a heartier feel.

Typical ingredients include azuki beans, sugar, and water, with optional additions such as salt, mochi, or shiratama dumplings. Some regional preparations top the dish with kinako (roasted soybean flour) for extra flavor. The dish is usually prepared hot and enjoyed as a warming winter treat.

Oshiruko is closely related to zenzai, and in different regions the two terms are used with varying meanings. In some areas, oshiruko refers to the smooth, strained bean soup with mochi, while zenzai describes a thicker soup containing whole or crushed beans. Because usage varies, many eateries use the terms interchangeably.

Culturally, oshiruko is associated with cold weather and is commonly eaten during winter and around the New Year. It is widely available in traditional Japanese confectionery shops, at food stalls, and in homes, often as a comforting end to meals. The dish reflects the broader Japanese custom of pairing sweet red beans with rice-based confections.
