When it comes to summer wagashi, few are as iconic as translucent kuzu mochi.
Its bouncy texture and cool mouthfeel make you forget the summer heat. But did you know that achieving a professional finish requires several important techniques?Hon-kuzu powderFrom how to choose the powder, to the kneading technique that produces a smooth texture, to the temperature control that draws out beautiful translucency, kuzu mochi making is packed with deep, sophisticated craft.
In this article, drawing on the expertise Minoyo has cultivated over 120 years since its founding, we share the secrets to making cooling summer sweets that delight your customers. We will introduce practical know-how to help wagashi shops and confectionery manufacturers create kuzu mochi they can confidently offer as a summer staple.
What Is Kuzu Mochi? Understanding the Difference Between Fermented and Non-Fermented
Kuzu mochi can be broadly divided into two types.
One is the Kansai-style kuzu mochi made with hon-kuzu powder. The other is the Kanto-style "kuzumochi" made from fermented wheat starch. Kuzu mochi made with hon-kuzu powder is prepared by mixing kuzu powder, water, and sugar and heating them to a translucent, bouncy texture. The Kanto-style kuzumochi, on the other hand, uses wheat starch fermented over a long period of as much as 450 days, giving it a distinctive flavor and texture.
Fermented kuzumochi is rich in plant-based lactic acid bacteria and has attracted attention for its health benefits as well. The lactic acid bacteria cultivated through a traditional production method passed down since the Edo period are said to help balance the internal environment of the body, and many people say, "I feel better when I eat kuzumochi."
This article will focus mainly on the method for making Kansai-style kuzu mochi with hon-kuzu powder.
How You Choose Your Hon-kuzu Powder Determines the Finish
Identifying High-Purity Hon-kuzu Powder
The first step in making kuzu mochi is choosing good-quality hon-kuzu powder.
Commercially available kuzu powder ranges widely, from 100% pure hon-kuzu powder to blended products mixed withpotato starchor cornstarch. Hon-kuzu powder is a starch extracted from kudzu root, and because the yield is small and it takes considerable effort, its price is on the higher side. In return, however, it offers excellent translucency and elasticity, achieving a smooth texture.
When choosing hon-kuzu powder, always check the ingredient labeling. Choosing a product clearly marked "100% hon-kuzu powder" is the shortcut to a professional finish. With blended products, the translucency and texture are inferior, making it difficult to bring out the true appeal of kuzu mochi.
Storage and Freshness Management
Hon-kuzu powder dislikes moisture. After opening, place it in an airtight container and store it in a cool, dark place. Because absorbing moisture makes it prone to clumping and harder to dissolve, the key is to bring it back to room temperature before measuring it out for use.
The Kneading Technique That Produces a Smooth Texture
How You Mix with Water Is the Key to Success
The most important step in making kuzu mochi is the process of mixing the kuzu powder with water.
Because kuzu powder does not dissolve easily in water, it must be thoroughly dissolved before heating. After adding the kuzu powder and water to a pot, mix carefully with a whisk or rubber spatula so that no lumps remain. At this point, since the kuzu powder tends to settle to the bottom, it is important to keep stirring right up until you begin heating.
If the mixing is insufficient, lumps may form during heating or the translucency may be lost. If lumps remain, straining the mixture through a mesh ladle or tea strainer will produce a smooth finish.
Timing of Heating and Kneading
Once the kuzu powder and water are mixed, place the pot over medium heat and begin heating.
It is important to keep stirring constantly from the bottom of the pot. Press a wooden ladle against the bottom of the pot and knead firmly in a circular motion, applying force. As heating progresses, the kuzu powder begins to turn translucent and develops a stickiness. At this point, keep kneading firmly while taking care not to scorch it.
Once it becomes translucent, reduce to low heat and knead until it develops a sheen and elasticity. Neglecting this step results in a hard texture or insufficient translucency. Kneading until the kuzu powder becomes completely translucent and heavy is the secret to a professional finish.
Temperature Control for Beautiful Translucency
Controlling the Heating Temperature
The translucency of kuzu mochi is determined by managing the heating temperature.
The basic approach is to heat over medium heat at first, then switch to low heat just before boiling. If you heat rapidly over high heat, the kuzu powder will not heat evenly and the translucency will be lost. It can also cause scorching, so pay the utmost attention to the heat level.
The time it takes to become translucent varies depending on the amount of kuzu powder and the heat, but is generally around 10 to 15 minutes. When it turns translucent and glossy, it's time to remove it from the heat.
The Cooling Method Changes the Texture
The cooling method after heating also affects the quality of the kuzu mochi.
Once you pour it into a mold, we recommend chilling it rapidly by submerging the entire mold in ice water. Cooling it slowly can cause the surface to turn whitish. Rapid cooling allows you to maintain translucency while achieving a bouncy texture.
When chilling in the refrigerator, cool it in the mold and cut it into portions only after it has completely set. When cutting, wetting the knife with water as you go produces a clean finish.
Finishing with the Traditional Flavor of Kinako and Kuromitsu
What brings out the deliciousness of kuzu mochi is kinako (roasted soybean flour) and kuromitsu (brown sugar syrup).
Kinako is made by roasting soybeans and grinding them into powder, and its fragrant flavor enhances the delicate taste of kuzu mochi. At Minoyo, we roast domestic soybeans in-house and adjust the particle size and degree of roasting to provide kinako of a quality suited to each use. The higher the degree of roasting, the greater the fragrance, and the better it pairs with kuzu mochi.
Kuromitsu is a sweet syrup made by simmering and dissolving brown sugar. Put brown sugar and water in a pot, bring to a boil, then strain to make it smooth. Adding honey deepens the richness and body. Pour the cooled kuromitsu over the kuzu mochi and dust it with kinako to complete a traditional kuzu mochi.
The balance of kinako and kuromitsu can be adjusted to your customers' preferences. Using more kinako brings out the fragrance, while using more kuromitsu highlights the sweetness.
Foolproof Tips the Professionals Practice
Common Failures and How to Prevent Them
A common failure in making kuzu mochi is the formation of lumps.
This is caused by not mixing the kuzu powder and water thoroughly. It can be prevented by fully dissolving the kuzu powder before heating and stirring constantly during heating. If lumps do form, strain the mixture through a mesh ladle before pouring it into the mold.
Another failure is a lack of translucency. This is caused by insufficient heating or by too high a heat. It is important to heat slowly over medium heat and knead firmly until it becomes translucent.
Storage Method and Shelf Life
Kuzu mochi is most delicious freshly made, but it can also be stored.
For refrigerated storage, we recommend arranging it on a plate, covering it with plastic wrap, and eating it within one day. There is also a method of storing it submerged in water, but this worsens the texture, so it is better avoided. For frozen storage, arrange the pieces so they don't stick together, cover with plastic wrap, and once frozen, gather them into a bag. It can be stored for about a month, but when thawing, lightly warming it in the microwave or reheating it by boiling will bring it closer to its original texture.
