Red bean ice cream, or aisu kōri azuki, is a beloved Asian dessert known for its subtly sweet and earthy flavor. This creamy, refreshing treat offers a unique alternative to traditional ice cream flavors. This comprehensive guide will walk you through creating your own homemade red bean ice cream, ensuring a perfect balance of sweetness and the distinctive taste of adzuki beans. We'll cover everything from selecting the right ingredients to mastering the perfect texture.
What are Adzuki Beans?
Before diving into the recipe, let's understand the star ingredient: adzuki beans. These small, red beans are a staple in East Asian cuisine, known for their slightly sweet and earthy flavor. They are a nutritional powerhouse, packed with fiber and protein. Finding high-quality adzuki beans is key to achieving the best flavor in your ice cream. Look for beans that are vibrant red and free of blemishes.
How to Make Red Bean Paste (Anko)
The foundation of delicious red bean ice cream is the anko, or red bean paste. Making your own anko allows you to control the sweetness and texture, resulting in a superior ice cream experience.
Ingredients for Anko:
- 1 cup adzuki beans, rinsed
- 3 cups water
- ¾ cup granulated sugar (or to taste; adjust based on your preferred sweetness)
- 1 tablespoon unsalted butter (optional, for richer flavor and smoother texture)
Instructions for Making Anko:
- Soak the beans: Rinse the adzuki beans thoroughly and soak them in plenty of cold water for at least 6 hours, or preferably overnight. This step helps them cook evenly.
- Cook the beans: Drain the soaked beans and place them in a pot with 3 cups of fresh water. Bring to a boil, then reduce heat to low, cover, and simmer for 45-60 minutes, or until the beans are very tender.
- Mash the beans: Once cooked, drain the beans, reserving about ½ cup of the cooking liquid. Use a potato masher or immersion blender to mash the beans until mostly smooth, but with some texture remaining. You can adjust the texture to your preference.
- Add sugar and butter: Add the sugar and butter (if using) to the mashed beans. Stir well over low heat until the sugar dissolves and the mixture is smooth and glossy. If the mixture is too thick, add a little of the reserved cooking liquid until you reach your desired consistency.
Let the anko cool completely before proceeding to the ice cream recipe. You can store leftover anko in an airtight container in the refrigerator for up to a week.

Frequently Asked Questions
How can I make vegan red bean ice cream?
You can easily adapt this recipe for vegans by substituting the heavy cream and whole milk with full-fat coconut milk. Use a plant-based sweetener like maple syrup or agave nectar instead of granulated sugar.
How long does homemade red bean ice cream last?
Homemade red bean ice cream, stored in an airtight container in the freezer, should last for 2-3 weeks. However, it's always best to consume it within the first two weeks for optimal flavor and texture.
Can I use canned red beans instead of dried adzuki beans?
While you can use canned red beans, the flavor and texture will differ from those made with dried adzuki beans. Canned red beans often have a softer texture, which may affect the final consistency of your anko and ice cream. For the best results, use dried adzuki beans.
How do I adjust the sweetness of the ice cream?
The sweetness of your red bean ice cream depends on the sweetness of your anko and the amount of sugar added to the cream mixture. Taste the anko before adding it to the ice cream base and adjust the sugar accordingly. Start with less sugar and add more to your liking.
Where can I buy adzuki beans?
Adzuki beans are readily available at many Asian grocery stores and increasingly in larger supermarkets in the international food section. You can also find them online.
