Fructose Free Classic Dashi
This deeply savory Japanese stock is built on just three ingredients — cold water, kombu, and bonito flakes — making it one of the most naturally clean broths you can prepare at home. The slow, gentle extraction process pulls umami from the sea kelp without ever letting the water boil, which keeps the flavor delicate and clear rather than bitter or murky. For anyone managing fructose sensitivity, this broth is a genuine kitchen staple because there are no onions, garlic, or high-fructose vegetables hiding in the base — just pure, oceanic depth. Many store-bought stocks and soup bases sneak in sweeteners or vegetable blends that can cause real problems, so making your own from scratch puts you fully in control. The technique is more meditative than difficult: a soak, a slow warm, a steep, and a strain. What you end up with is a luminous, golden liquid that forms the backbone of miso soup, noodle broths, and simmered dishes. Make a batch, refrigerate it, and you'll have a fuss-free, gut-friendly foundation ready to go all week.

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.
- 2
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.
