Zenzai or Oshiruko is a traditional Japanese sweet soup, typically enjoyed warm during colder months. It features soft, slow-cooked azuki (red) beans in a sweet, clear or slightly thickened broth, often served with mochi (rice cakes) or shiratama (glutinous rice dumplings). The dish is a staple in Japanese cuisine, particularly during New Year celebrations and winter festivals.
This dish is high in carbohydrates due to the sweetened beans and added mochi, providing a quick energy boost. It offers a good source of plant-based protein and fiber from the azuki beans, with a typical serving containing around 200-300 calories depending on sweetness and portion size.
