"Rosanjin Natto Bowl" is a product developed to reproduce the "ultimately delicious way to eat natto" that was advocated by the artist "Kitaoji Rosanjin" who is also known as a foodie. If you set natto on the main body and turn the handle, you can stir at double speed.
Based on Rosanjin's teaching that "natto tastes better the more you stir it," we set the number of times to stir 424 as a result of verifying the number of stirs that make it the most delicious. When you turn the handle, the number of rotations of the gear is counted, and the lid of the main body opens automatically at the best timing (305 times) to add soy sauce and the timing of completion (424 times). The finished natto has a strong richness, and the soy sauce is often entwined to give it a mellow taste.
According to the company's survey, natto mixed 424 times has a richness of 109% compared to the unmixed state. Also, Takano Foods, the largest natto industry, said that the taste was "certified".
The company plans to introduce its own natto recipe using this product with the full cooperation of Takano Foods.
