The Science of Taste

Umami Synergy: 1 + 1 = 7

Combining “Glutamic acid” (Kombu) with “Inosinic acid” (Bonito) or “Guanylic acid” (Shiitake) boosts the umami intensity by **7 to 8 times**. This is the magic of “Awase Dashi” (Mixed Dashi), the basis of Japanese cuisine.

The Golden Ratio Rule

Generally, combining Vegetable (Kombu) and Animal (Bonito, etc.) ingredients is basic.
Ex: Base with Kombu dashi, finish with Bonito flakes.
