Instructions
- Step 1: Rinse kombu under cold water, then place in a pot with 1.2L water. Bring just to a simmer (do not boil) over low heat for 15 minutes, removing kombu before it starts to boil to prevent bitterness.
- Step 2: Simmer dried shiitake mushrooms in the dashi for 10 minutes until softened, then remove and slice thinly.
- Step 3: Cut carrots and daikon into 1/4-inch thick coins. Add to the dashi pot with sliced shiitake, soy sauce, and mirin. Simmer uncovered for 15 minutes until vegetables are tender but still hold shape.
- Step 4: Gently fold in natto and cook for 2 more minutes until heated through and natto's sticky texture coats the vegetables.
