dashi or chicken stock

Dashi is a fundamental Japanese stock made by steeping kombu (kelp) and bonito flakes (katsuobushi) in hot water, though variations exist using other ingredients. The most common form, ichiban dashi (first extraction), is made by briefly infusing kombu and dried bonito flakes in near-boiling water (around 70–80°C) for 10–15 minutes, then straining. The resulting broth is clear, light golden in color, and delicate in flavor—distinctly umami-rich due to the glutamates in kombu and inosinate compounds in bonito. Secondary extractions (niban dashi) use the spent solids steeped longer for a deeper flavor. Regional and ingredient variations include awase dashi (blended kombu and bonito), shiitake dashi, and vegetarian alternatives using only kombu or with added dried shiitroom or small fish (niboshi). The balance and simplicity of dashi—typically made with just two or three ingredients and minimal seasoning—distinguishes it from Western stocks.

Dashi serves as the foundation for Japanese cuisine, essential to soups (miso soup, clear suimono broths), noodle dishes (udon, soba), simmered dishes (nimono), and chawanmushi (savory egg custards). It is used to season and thin sauces, and as a cooking liquid for vegetables, tofu, and fish. The delicate umami backbone allows complementary flavors to shine without overwhelming dishes. Ichiban dashi, with its subtle sweetness and clean taste, is preferred for delicate broths; niban dashi works well in simmered dishes and dipping sauces. Proper preparation—avoiding boiling, which makes the stock cloudy and bitter—is critical to achieving the characteristic clarity and refinement of dashi-based dishes.
