Introduction

Zenzai, also known as Oshiruko in Japan, is a comforting and sweet red bean soup featuring delicate mochi. This traditional dish is often enjoyed during the winter months or at New Year’s celebrations, where its warm, rich flavors evoke a sense of nostalgia and comfort. You can find it in cozy Japanese tea houses or festive street stalls, typically priced between 500-1,000 yen ($5-$10). As you explore this delightful treat, you might also be interested in the keto version of Zenzai, which maintains the beloved flavors while keeping the carbohydrates low. Whether you’re warming up on a chilly evening or celebrating a special occasion, both versions of Zenzai promise to deliver smiles and satisfaction.

Origin and Inspiration

The roots of Zenzai trace back to Japan, where sweet red bean soup has been cherished for centuries. Made primarily from azuki beans, this dish embodies the Japanese practice of enjoying seasonal ingredients. Traditionally served as a comfort food, Zenzai transforms simple beans and sugar into a soul-soothing delight. Similar dishes can be found in various cultures, such as the Chinese red bean soup or the Filipino "manggang hilaw," but Japan’s Zenzai stands out for its unique pairing with chewy mochi.

In adapting Zenzai to a keto lifestyle, we preserve the essence of the traditional recipe while using sugar substitutes to achieve the desired sweetness without the high carbohydrates. Imagine savoring the same velvety smooth texture and the tender bites of mochi—only now they fit seamlessly into a low-carb regimen.
