- 3 cups water
- 1/2 cup sugar (adjust to taste)
- 1/4 teaspoon salt
- 1 cup mochi, cut into small pieces

Ingredient Notes and Substitutions
- Adzuki beans: These are the star of the dish, providing a sweet and earthy flavor. If unavailable, you can use canned red beans.

- Mochi: The chewy texture complements the soup perfectly. You can use store-bought or make your own.
How to Make Zenzai
Step 1: Rinse the Beans
Start by rinsing the adzuki beans under cold water to remove any dirt or impurities. This helps to ensure a clean flavor in your dessert.
Step 2: Soak the Beans
Soak the beans in water for at least 4 hours or overnight. Soaking helps to soften the beans, reducing the cooking time.
Step 3: Cook the Beans
Drain the soaked beans and place them in a medium saucepan with 3 cups of fresh water. Bring it to a boil and then reduce to a simmer for about 40 minutes or until tender.
Step 4: Add Sugar and Salt
Once the beans are tender, stir in the sugar and salt. This step enhances the sweetness and balances the flavors.
Step 5: Simmer the Mixture
Let the mixture simmer for an additional 10 minutes, allowing the flavors to meld together. Stir occasionally to prevent sticking.
Step 6: Prepare the Mochi
While the bean soup simmers, prepare your mochi by cutting it into small pieces. You can steam or grill it for extra flavor and texture.
Step 7: Serve the Zenzai
Once the soup is ready, ladle it into bowls and top with the mochi pieces. This creates a beautiful presentation and adds that delightful chewy texture.
Step 8: Add Toppings
If desired, drizzle some sweetened condensed milk over the top for an extra touch of sweetness. This is optional but highly recommended!
Pro Tip: Adjust the sweetness to your preference by tasting the soup as you add sugar.
Tips for the Best Zenzai
- Use fresh adzuki beans for the best flavor; dried beans can be used but may take longer to cook.
- Don’t rush the soaking process; it’s key for tender beans.
- Experiment with the sweetness level to find your perfect balance.
- For a unique twist, add a splash of vanilla extract for added depth.
- Serving it warm is traditional, but chilled Zenzai is refreshing on hot days.
Common Mistakes to Avoid
- Not soaking the beans long enough can lead to tough beans. They need time to soften properly.
- Adding too much sugar at once can make the soup overly sweet. It’s better to add gradually and taste.
- Skipping the simmering step can lead to underdeveloped flavors. Allow time for everything to meld.
- Not stirring while cooking can cause the beans to stick and burn. Keep an eye on it!
