For a more robust flavor, consider allowing the kombu to soak in the dashi stock for a few hours or overnight before cooking. You can also add tofu or other vegetables such as carrots or bok choy for a heartier soup. Adjust the seasoning to your preference and remember that the key to a great Japanese mushroom soup is balancing the delicate flavors of the mushrooms and the broth.
