The world of "cooling materials" essential to summer wagashi
The most important thing in making summer wagashi is to convey a sense of coolness through appearance and texture. Using materials with transparency lets you express refreshment both visually and in taste.
Particularly noteworthy areGenuine warabi starch, hon-kuzu (kudzu starch), and agar—traditional materials. These have high transparency and a distinctive springy texture that makes you forget the summer heat.
Let us introduce, in concrete terms, the tips for material selection that professional wagashi artisans put into practice.

Hon-warabi-ko and kuzu-ko | The leading materials that create transparency
Hon-warabi-ko is known as the finest material for making warabi mochi.
Hon-warabi-ko, extracted from genuine bracken root, is characterized by a distinctive transparency and springy texture. It is highly rare and is the top-grade product used at high-end wagashi shops. Minoyo offers hon-warabi-ko in a 10kg specification, ensuring consistent quality for commercial use.
Meanwhile, hon-kuzu (kudzu starch) is an essential material for kuzu mochi and kuzukiri. Hon-kuzu, represented by Yoshino kuzu, is prized for its transparency and smooth texture. Minoyo handles hon-kuzu in a 5kg×4 specification, and a top-grade product calledZuiichi Hon-kuzuis also available.
By using these materials appropriately, you can freely control the texture and transparency you seek.
The characteristics and uses of hon-warabi-ko
Warabi mochi made with 100% hon-warabi-ko has high transparency and a distinctive chewiness. Adding water and sugar and kneading while heating, the way it gradually becomes transparent is spectacular.
After chilling and setting it, the standard way to enjoy it is topped with kinako (roasted soybean flour) or brown sugar syrup. As a cooling summer confection, it makes a dish your customers will love.
Points on how to use hon-kuzu
Hon-kuzu is dissolved in water and then heated, setting into a transparent jelly. Besides enjoying it as kuzu mochi, kuzu jelly with fruit sealed inside is also popular.
Minoyo also offers hon-kuzu powder (20kg specification), which is easier to handle and improves work efficiency. When large-scale production is needed, the powder type is convenient.

Agar | How to choose this summer staple material
Agar is an essential material for summer wagashi.
Agar, made from tengusa seaweed, has the property of setting even at room temperature, making it ideal for summer wagashi production. Minoyo handles thread agar (1kg and 5kg specifications) and powdered agar, so you can choose according to your purpose.
Thread agar has a traditional form and is used after being reconstituted in water. It also looks cool and can be served as-is in dressed dishes. Powdered agar, on the other hand, is easy to measure and offers good work efficiency.
Mizu yokan and kingyoku-kan made with agar become summer staple products with their transparency and refreshing texture.
Basic ways to use agar
It is important to dissolve agar in water, bring it to a boil, and fully dissolve it. Add sugar or an, pour into molds, and chill to set. Because it sets at a high temperature, it is easy to handle even at room temperature.
Kingyoku-kan with fruit or an sealed inside is beautiful to look at and is also popular as a summer gift.
Yuzu and plum | Adding refreshment with summer-oriented flavorings
Essential to summer wagashi is a citrus aroma.
Minoyo offers an abundant range of yuzu processed products made with domestic yuzu, including yuzu slices (11kg specification), yuzu jam (2kg and 20kg specifications), fresh yuzu paste (11kg specification), and yuzu juice (2kg×6 bottles, frozen). All require refrigeration or freezing and can be used while keeping their freshness.
Yuzu's refreshing aroma and pleasant acidity give summer wagashi a cool, clean feel. There are many ways to use it, such as topping yokan and fresh confections or mixing it into an.
Plum is also a material well suited to summer wagashi. Minoyo has a full lineup of plum processed products such as simmered plum in syrup, Kishu neri-ume (plum paste), plum flesh, and plum juice. The tartness of plum whets the appetite and is also effective in preventing summer fatigue.
Ideas for summer wagashi using yuzu
Yuzu manju, made by mixing yuzu jam into the an, is a gem with a refreshing aroma that spreads through it. Using fresh yuzu paste lets you enjoy a more authentic yuzu flavor.
Yuzu slices can be used as a topping for mizu yokan and kingyoku-kan, adding a visually cool touch.
Summer wagashi that make the most of plum
Simmered plum in syrup can be used as-is as an ingredient in wagashi. The balance of the plum's tartness and sweetness is exquisite, easing the summer heat.
Plum an made with Kishu neri-ume has a light, refreshing taste and is ideal for summer wagashi. Jelly and syrup made with plum juice also serve as materials that convey a sense of coolness.

Tips for achieving transparency | Learning professional techniques
There are several points to making wagashi with transparency.
First, material selection is important. Using high-quality materials such as hon-warabi-ko and hon-kuzu (kudzu starch) dramatically improves transparency. Minoyo offers the top-grade Zuiichi Hon-kuzu (5kg×3 specification), whose high purity leads to transparency.
Next, the heating and kneading process. When dissolving the material in water and then heating it, temperature control is important. Kneading at the right temperature increases transparency and produces a smooth texture.
The cooling method also affects transparency. Cooling slowly, rather than rapidly, produces a finish with even higher transparency.

Adding color with colorings
For summer wagashi, cool-toned colors are also important. Minoyo offers paste-type colorings such as Neri Hon-beni (paste red), paste yellow, paste blue, and paste hikicha color, and powder-type colorings such as Red No. 3, Blue No. 1, and Yellow No. 4.
