Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Adzuki beans | 1 cup (200 g) | Dry, small red beans |
| Water | 4-5 cups (960-1200 ml) | For soaking and cooking |
| Sugar | 1/4 to 1/2 cup (50-100 g) | Adjust to taste; options include white sugar, honey, or malt syrup |
| Optional ingredients | ||
| Glutinous rice balls (optional) | about 8 small balls | Pre-cooked or made fresh |
| Coconut milk (optional) | 1/2 cup (120 ml) | For added creaminess |
| Fresh fruit slices (optional) | as desired | e.g., mango, banana, or strawberries |
Instructions
Step 1: Preparing the Beans
Begin by thoroughly rinsing the adzuki beans under cold running water. Place the beans in a large bowl and cover with plenty of water, ensuring they are submerged by at least 2 inches. Allow the beans to soak for a minimum of 6 hours, preferably overnight, to soften them and reduce cooking time. Soaking also helps to remove any impurities or residual dirt.
After soaking, drain the beans using a fine mesh strainer, rinsing again briefly to wash away any residual surface starch or debris. Set aside for further use.
Step 2: Cooking the Beans
Transfer the soaked beans into a heavy-bottomed saucepan or pot. Add 4 to 5 cups of fresh water, ensuring the beans are fully submerged. Bring the water to a rolling boil over high heat, then reduce the heat to maintain a gentle simmer. Skim off any foam or scum that rises to the surface during boiling—this improves the clarity and texture of the soup.
Cover the pot loosely with a lid, leaving a small gap for steam to escape. Simmer the beans for approximately 20-30 minutes, or until they are tender but not falling apart. Test doneness by pressing a bean between your fingers or tasting a sample. The beans should be soft but hold their shape.
Monitor the water level during cooking, adding more hot water if necessary to prevent burning or sticking. Stir occasionally to prevent the beans from sticking to the bottom of the pot.
Step 3: Sweetening the Soup
Once the beans are tender, add your preferred sweetener directly into the pot. Start with 1/4 cup (50 g), then taste and adjust according to your sweetness preference. Stir well until the sugar dissolves completely. For a richer flavor, consider adding a splash of coconut milk or honey at this stage.
If you wish to add other ingredients like glutinous rice balls or fruit, do so now. Gently place the rice balls into the simmering soup, ensuring they are fully submerged. Continue to cook for an additional 10-15 minutes, or until the rice balls are tender and cooked through.
Step 4: Final Simmer and Serving
Allow the soup to simmer briefly to meld the flavors. Taste again and adjust sweetness or add a pinch of salt if desired to balance the flavors. Remove from heat and let it cool slightly before serving.
Serve the hot Adzuki Bean Soup in individual bowls using a ladle. Garnish with optional toppings such as coconut milk, fresh fruit slices, or a sprinkle of sesame seeds. The soup can also be enjoyed chilled or at room temperature depending on preference and occasion.
Preparation Tips
- Soaking beans: Always soak adzuki beans overnight for optimal texture and cooking efficiency. If short on time, soak for at least 2 hours, though longer soaking yields better results.
- Cooking liquid: Use fresh, hot water during cooking to prevent cloudiness and preserve flavor. Avoid using stale or previously boiled water.
- Sweetening: Adjust sweetness gradually, especially if serving children or those with dietary restrictions. Consider natural sweeteners like honey or maple syrup as healthier alternatives.
- Texture preferences: For a thicker, creamier soup, mash some of the beans with a fork or blend a portion of the cooked beans before serving.
