What is the #1 Selling "Chattsumi Dorayaki"?
The dorayaki has a moist and fluffy texture, kneaded with matcha, a specialty of Taiyo. It is paired with an incredibly smooth and rich matcha butter cream and plump, well-formed Hokkaido-produced adzuki bean paste. This exceptional deliciousness is the proof of its #1 sales. It is a masterpiece that boasts overwhelming popularity, winning out over numerous other dorayaki.
When you hear "butter cream," you might think, "Isn't it a bit too rich...?" But the "Chattsumi" dorayaki is different. It's rich yet not heavy. That's why you can't help but reach for "just one more..." That charm is packed into this "Chattsumi" dorayaki.
The First Pick Matcha "Ryokuju" That Makes Chattsumi Most Special
"Chattsumi" uses the exquisite matcha "Ryokuju," carefully selected by a tea master who is the "Tea Tasting Champion of Japan" from Matsuda Shoten Co., Ltd. It uses only the "first harvest" of the year, generously kneaded into both the dough and the butter cream.
What is "Tea Tasting Champion of Japan"?
"Tea Tasting Champion of Japan" is the title of the national champion in the tea tasting competition participated in by tea professionals nationwide, signifying the highest skill in tea appraisal. It is considered the highest title among tea professionals, requiring advanced senses and extensive knowledge/experience to discern taste, aroma, and color.
Special "First Pick" Matcha
The first harvest is the first tea harvested of the year, and it is the rarest and highest quality tea that can only be enjoyed at this time.
It is rich in "theanine," a umami component accumulated during winter, and all aspects – aroma, taste, and color – are top-class. Its fresh and deep aroma, reminiscent of new green leaves, is a special gift only available at this time.
Furthermore, the first harvest is also considered a lucky charm, said to bring one year of good health if drunk, making it a wonderful product that is very popular as a gift.
Quality that Meets the "Conditions of Good Matcha"
* Color: A vivid deep green remains even after baking.
* Aroma: A fresh, green leaf aroma that does not disappear even when heated.
* Taste: Rich umami that does not lose to the sweetness of the bean paste, and a natural sweetness with no sharp edges.
* Texture: Smooth mouthfeel due to finely powdered particles.
Because it is the first harvest tea that clears all these conditions, there is absolutely no bitterness or astringency characteristic of matcha, and it has a surprisingly milky and smooth mouthfeel. Yet, the rich umami of matcha spreads thoroughly, creating a luxurious taste.
The Taste Unique to First Pick Matcha ── The "Art of Taste" Woven by Rich Matcha Butter Cream and Taiyo's Signature Moist, Fluffy Dough
The charm of "Chattsumi" is, above all, its rich flavor unique to first pick matcha.
The dough and butter cream are luxuriously blended with three types of matcha, each with different aromas, umami, and colors, carefully selected by a master who knows tea leaves inside and out. In particular, by using the first harvest of "Ryokuju," it achieves a special taste that stands out in all aspects: aroma, flavor, and color.
First, please try tasting just the "dough" alone.
From the photo, you can see the fragrant baked color, moist sheen, and fluffy texture. Furthermore, even after baking, a vivid deep green remains.
One bite, and its texture, which lightly touches your lips, is like exquisite silk. From the moist and soft dough, a fragrant flavor and matcha aroma gently waft into your nose.
"Even the dough alone is delicious" – that's Taiyo's commitment to its dorayaki.
And inside, as you've been waiting for.
A generous amount of rich matcha butter cream and adzuki bean paste.
The true essence of "Chattsumi" is precisely this matcha butter cream. The moment it melts in your mouth, you realize, "Ah... this is Chattsumi."
The indescribable happiness brought by the surprisingly smooth butter cream that melts with the heat of your tongue. It has a rich matcha umami that doesn't lose to the sweetness of the adzuki beans, yet it's not heavy. The reason is the clear umami and sweetness unique to first pick matcha that fills your mouth.
Paired with this is the adzuki bean paste, made from Hokkaido-grown beans, which has a plump texture and fine grain. As you chew, a moist texture and rich sweetness emerge, melting into the melting butter cream. Japanese umami and Western richness harmoniously blend, making the sweetness of the bean paste more elegant, and the umami transforms into a deep flavor that layers upon itself.
Dough, butter cream, adzuki bean paste.
While each has a star-level deliciousness, the moment they all come together, the trinity's harmony is like drawing "a miraculous golden ratio" in your mouth. The deep satisfaction that can only be achieved through exquisitely calculated balance – that is the deliciousness of "Chattsumi."
A Distinction of "Two Treasures" – Exquisite Matcha Butter and Traditional Adzuki Bean Paste
■ Matcha Butter Cream Using 100% Domestic Butter
A matcha butter cream luxuriously made with 100% carefully selected domestic butter, with a rich yet light melt. By carefully whipping in air, it achieves a rich yet not heavy taste. It also has a smooth, melting texture, unlike the often crumbly texture of butter cream.
Adding starch syrup provides a gentle sweetness, creating a rich yet elegant flavor that everyone from children to adults will love. While matcha sweets can sometimes be too bitter, Chattsumi has none of that.
■ Adzuki Bean Paste Made from Hokkaido-Grown Beans, a Renowned Region for Azuki Beans
Taiyo's adzuki bean paste is a whole bean paste cultivated in fertile land and climate, characterized by its plumpness, good grain size, and natural sweetness and rich flavor. Even amidst the rich butter cream, you can clearly feel the plump texture of the whole bean paste. The richness of both Japanese and Western elements enhances each other, creating an elegant sweetness and a deep flavor. It's an exquisite bean paste that makes the most of the superior taste of Hokkaido-grown azuki beans.
Taiyo's Special "Moist and Fluffy" Dough
The reason our dorayaki stands out from the rest is, above all, the "fluffiness" and "moisture" of the dough. It's as light and fluffy as sponge cake that has incorporated air, and when you bite into it, it's moist and has a crisp texture – we are thoroughly committed to this exquisite balance.
The vertical lines that appear when you cut a dorayaki in half are the air bubbles that create its fluffy texture. The fact that these air bubbles are uniformly present vertically in the dorayaki skin is proof of its fluffy mouthfeel and crisp texture.
To achieve this ideal texture, we went through numerous trials and errors to arrive at this special dough.
By resting the dough overnight before baking, moisture is thoroughly distributed throughout, achieving a fluffy texture. Furthermore, by adding a small amount of "sake" (Japanese rice wine), which is not commonly seen elsewhere, we add a deep umami to the moisture.
As it bakes, the dough puffs up so wonderfully and largely while incorporating plenty of air.
While achieving a fragrant and beautiful baked color on the surface, the vibrant green of the matcha is firmly retained inside – this exquisite baking is born only from the skill of artisans who manipulate delicate heat and the high-quality first harvest tea "Ryokuju" that does not fade with heat.
After generously piping the bean paste, it is gently wrapped in the freshly baked dough.
Gently and softly wrapping it without crushing the dough is also an important manual task. "Chattsumi" is precisely "a piece that shines with skill," sealing the matcha's color, aroma, and flavor as they are through such handiwork.
The beauty of its appearance and the umami of matcha that spreads in your mouth. Achieving both is a crystallization of dedication that cannot be easily imitated.
A Taste of Auspiciousness Passed Down Through Generations – Suitable for Special Gifts
Dorayaki, with its two pieces of dough sandwiching bean paste, has long been cherished as an "auspicious confectionery" that evokes marital harmony and family bonds, and is often enjoyed as a gift for loved ones.
"Chattsumi" can be enjoyed individually, but for special gifts, we offer a dedicated gift box. We also accept gift sets that combine it with our original "Ogura Dorayaki," as shown in the image, and they are highly appreciated for celebrations and as souvenirs.
This season, for celebrations of new beginnings such as entrance into school or employment. The "first harvest" used in Chattsumi is an auspicious tea, picked first of the year. It is a special matcha that also carries the wish for a new future to grow as grandly as new buds. It is a suitable item for a spring gift to celebrate a loved one's new start.
Also, as a Mother's Day gift for mothers who love matcha, or as a souvenir for Golden Week visits home. We offer exquisite items, carefully crafted one by one by Chiba artisans, that convey a sense of specialness, tailored to the occasion and budget.
Beautiful Until the Moment of Gifting – Commitment to Design
"Chattsumi" lives up to its name with its thoughtful presentation. The elegant packaging, reflecting the beautiful green of matcha, is enhanced by the dignified golden "Chattsumi" lettering. The exhilaration upon receiving it makes it a truly special gift. We carefully craft it with sincerity so that the giver's feelings are directly conveyed.
"Staff all say it's their favorite, our proud dorayaki."
Please try it at least once!
Actually, "Chattsumi" is a masterpiece that we deliver with such confidence that all our staff say, "This is my favorite dorayaki." We recommend it not only to matcha lovers but also to those who don't usually pick up matcha sweets. After one bite, you're sure to want to eat it again.
On "Dorayaki Day," which carries the wish "that everyone will be happy by eating dorayaki." This is a special item delivered with such a wish for "shiawase" (happiness).
