The simplest dashi is vegan and is essentially just boiling kombu (seaweed) in  hot water. Dashi is delicious soup base for your next homemade ramen, miso soup, cooking liquid for sauces, or a protein marinade! 

More complex dashi recipes might call for bonito flakes (fermented and dried fish, and shaved into flakes), dried mushrooms, toasted soy beans, and more. Here are the steps for a simple vegan dashi!
