Latex Free Classic Dashi
This deeply savory Japanese stock is built on just three ingredients — cold water, kombu, and bonito flakes — yet it delivers a clean, umami-rich broth that forms the backbone of countless dishes. The technique is all about patience and gentle heat: the kombu is scored and cold-soaked to coax out its oceanic depth, then removed before the water ever reaches a boil, keeping bitterness at bay. Bonito flakes are added off the heat and left to steep quietly until they drift to the bottom, producing a broth that is crystal clear and remarkably delicate. For anyone navigating latex sensitivities, this recipe is a genuinely safe and satisfying option — no thickeners, no additives, no ingredients that commonly cross-react, just whole, minimally processed pantry staples. The finished dashi is endlessly versatile: use it as a base for miso soup, noodle broths, simmered vegetables, or dipping sauces. It keeps in the refrigerator for up to three days, so a single batch can quietly elevate your cooking all week long.

4 servings
- 4 cups cold water
- 1 oz (about 15–20 g) kombu
- 1 oz (about 1 packed cup) katsuobushi (bonito flakes)
Instructions
- 1
Use kitchen scissors or a knife to score the kombu with a few shallow cuts along its surface, then place it in a medium saucepan with the cold water. Let it soak for 30 minutes, until the kombu has softened and the water has taken on a faint golden tint.

Set the saucepan over medium-low heat and warm the kombu and water slowly, until small bubbles begin to form at the bottom of the pan and the water reaches about 140–150°F (60–65°C) — just below a simmer. This should take about 10 minutes. Do not let the water boil.
