There are six types of sponge cakes in total, including matcha, chocolate, black tea, and hojicha, but 70 to 80% of repeat customers prefer the plain type. Father Tadaaki and son Yoshitaka work in perfect harmony, surrounded by scales and ovens that have been carefully used since the company's founding. Currently, Yoshitaka is in charge of the work in front of the oven, which greatly affects the quality of the product, while Tadaaki supports Yoshitaka in making the dough.

Because we don't use any additives, adjusting the baking time is the most difficult part. If you take it out one minute early, the surface becomes bumpy, and if you put it in one minute longer, it becomes hard," says Yoshitaka. I made many mistakes in the past," says Yoshitaka. When he started his own business, the number of customers increased rapidly, and at the peak of his busy schedule, he baked sponge cakes all hours of the night. Tadaaki's lean and steady movements are the essence of a craftsman.

As I admired the sponge cakes after they were removed from the oven, Nariko gave me some advice. Even though we have developed a technology that can keep for a long time, I want you to eat it as soon as possible. The earlier you eat it, the better it tastes.

1. weighing
Measure out the amount of top white sugar, granulated sugar, flour, honey, and syrup suitable for 75-80 eggs to be used at one time, the old-fashioned way.

2. Dough making
In a well-used machine, first mix the eggs and sugar for 10 to 15 minutes, then add the flour when it starts to become lumpy.

3. Strain
When there are no lumps, remove the ball part from the mixing machine and strain half of the mixture.

4. Pouring into a wooden mold
Using a wooden spatula, pour the smooth dough into the wooden mold without wasting any ingredients.

5. bake
Bake in a 170-180 degree oven for about 1 hour. Mix in the middle to distribute the heat evenly, misting with water along the way.
