The red Azuki bean is a treasured dessert ingredient in many East Asian sweets. Its sweet red bean paste is ready to make a nice and tasty center for everything from Chinese moon cakes to Japanese Daifuku rice cakes. There must be a way for such a delicious flavor to work in ice cream, right? Read on to find out!
The Azuki bean, which is also called the Adzuki, Aduki, or red mung bean, is popular in East Asia. It seems to be also popular in Hawaii and the Philippines. We all know that beans are generally good for us and healthy. They are high in fiber, plant protein, minerals, and vitamin B. This is also true for the red Azuki bean, which has gotten the most attention because it tastes great when made into a paste and mixed with sugar, even though the added sugar makes the overall picture look less healthy. The bean tastes mild and slightly nutty, and when you combine it with something sweet, it’s like food heaven!
Among the panoply of ice cream flavors, red bean stands out for its distinctly nutty, subtly sweet profile This Asian dessert staple intrigues many ice cream lovers with its unique color and texture. But what exactly gives red bean ice cream its signature appeal? Let’s unravel the ingredients, taste, texture and origins of this cooling, creamy treat
The Starring Role Goes to Adzuki Beans
As the name implies red bean ice cream contains adzuki beans as the predominant ingredient. Adzuki beans are a type of small oval red bean frequently used in Chinese, Japanese and Korean cuisines. Their nutty flavor and smooth texture make them perfectly suited for desserts. To make red bean ice cream, dried adzuki beans are boiled until soft, then mashed into a coarse paste. The bean paste provides the base flavor and distinct reddish-brown hue. Some versions also incorporate whole adzuki beans for added texture. This simple legume gives red bean ice cream its distinctly nutty essence and humble beginnings.
Coconut Milk and Condensed Milk Enhance Creaminess
While red bean ice cream contains no dairy, it achieves a smooth, creamy texture thanks to coconut milk and sweetened condensed milk. Full-fat coconut milk provides healthy fats for a lush, milkshake-like consistency without the lactose. Sweetened condensed milk also amps up the velvety richness. The combination mimics the effects of cream or custard. Eggs may be used as well for extra emulsification. The end result is a dense, Almost chewy ice cream with a melt-in-your-mouth feel reminiscent of gelato. The coconut and condensed milks work harmoniously with the beans to create a sublime icy treat.
Rock Sugar Syrup Lends Subtle Sweetness
To balance out the earthy, savory quality of adzuki beans, red bean ice cream incorporates sugar for a touch of sweetness. Traditional recipes use rock sugar syrup made by boiling rock sugar crystals in water. Rock sugar derives from sugarcane and offers complexity similar to brown sugar. The crystallized syrup melts during freezing to gently sweeten without overpowering the nutty bean flavor. Other simple syrups, like those made from agave or maple, can be substituted. Granulated white sugar often provides sweetness in modern versions. Either way, just a bit of sugar allows the adzuki flavor to shine.
Toppings and Variations Abound
Part of the appeal of red bean ice cream is how it lends itself to creative embellishments. Most shops top scoops with a drizzle of condensed milk and puffs of whipped cream for added luxury. Crumbled cookies or mochi (chewy rice cakes) provide crunch. Cornflakes add wholesome texture. Azuki beans may be mixed in for extra body. Some brands swirl red bean with green tea or black sesame for a colorful twist. Premium versions even layer red bean ice cream with matcha or hojicha tea lattes. The options for toppings and mix-ins are virtually endless.
A Long History as a Chinese Dessert Favorite
Red bean ice cream has roots as a traditional Chinese sweet snack called douhua. Records trace this adzuki bean pudding back over 1,000 years to the Han Dynasty. Street vendors in China commonly sold douhua topped with syrup as an affordable indulgence. The nutritious and satiating dessert was also believed to have healing properties. Over time, the basic douhua evolved into frozen red bean ice cream to suit modern tastes. This new form gained popularity in Hong Kong, Taiwan and Southeast Asia. Red bean ice cream is now enjoyed worldwide while retaining its status as a classic Chinese treat.
Rising Popularity as a Japanese Souvenir Item
In the 1980s, red bean became a trendy ice cream flavor in Japan after decades of being viewed as an old-fashioned taste. Specialty shops reinvented the treat using high-quality ingredients and unique styles. In Japan, red bean ice cream is typically less sweet than Chinese versions, allowing the adzuki flavor to take center stage. The dessert grew into a favorite souvenir for tourists to take home after trying the smooth, aromatic ice cream on their travels. For many, red bean ice cream now epitomizes the pleasures of a Japanese vacation.
Where to Sample Authentic Red Bean Ice Cream
For the full experience, try red bean ice cream at a specialty shop or Asian bakery. Chicago is home to tiny Chiya Chai Café, which serves the ice cream in homemade waffle cones. Chinatown Ice Cream Factory in New York City features traditional Chinese preparation. Palette Tea House in San Francisco beautifully layers red bean with hojicha tea. Little Tokyo in Los Angeles has Mikawaya for classic Japanese-style. Most Chinatowns, Koreatowns or Japantowns will offer tempting red bean options. You can also DIY red bean ice cream at home using canned adzuki beans and your favorite toppings. However you scoop it, red bean ice cream is a cool, nutty treat bound to delight.
How to do it
Once you have smooth Azuki bean paste, all that’s left to do is make the custard base. Mix the egg yolks, dairy, and sugar together, and then start cooking!
As always, the goal is to get to the “Nappe” stage. At this point, the base should not only be pasteurized (thanks to the egg yolks!), but it should also have gained that very important thickness that lets us know the egg yolks are stabilizing it and that the final consistency will be nice and smooth.
Other general rules of thumb and the Spoon test might be useful, but I usually use a thermometer to make sure the base gets to 82–84oC/180-183oF.
After the base’s custard is done, all that’s left to do is add the red bean paste and whisk!
We are now ready to make the base. For the best results, let it cool down and then put it in the fridge for at least two hours before using an ice cream machine.
… and my own quest for bean paste
My own first attempt to make red bean paste a few years ago ended in total and utter failure – the whole family quickly agreed that the resulting ice cream was the most disgusting ice cream that I’d ever made. And I could only agree … That said, it should be perfectly possible to make Azuki bean paste yourself, and I really encourage those who think they are up for it to do so.
You can also do what I did this time and buy some already made at an Asian store. (I got too burned the last time I tried to make bean paste at home, so I honestly don’t know if I’ll ever do it again.) Plus that my family probably would have boycotted the subsequent ice cream out of hand …).
