sweet red bean soup; oshiruko
A traditional Japanese sweet soup made from sweetened azuki beans, typically served hot with mochi (rice cakes) or shiratama dango (rice flour dumplings). A classic winter comfort food.
The お is a beautifying prefix; the base form is 汁粉, but お汁粉 is the standard spoken form. The names differ by region. In Kansai, お汁粉 is made with smooth bean paste and 善哉 with whole beans. In Kanto, both kinds are お汁粉, and 善哉 usually means mochi topped with thick bean paste and little liquid. Commonly served at 甘味処 (traditional sweets shops) and during 正月 (New Year). Often associated with warming up in cold weather.
