Dashi Recipe: The Japanese Umami Broth

Dashi is a soup stock that is essential in Japanese cuisine. You’ll find it as a base for many dishes, such as miso soup, noodle soup, hot pot, and a variety of sauces. Dashi gives a savory or umami flavor to the food, thanks to the glutamic acid and inosinic acid from the ingredients it’s made from. 

Dashi is usually made of water, kombu (dried kelp), and katsuobushi (dried bonito flakes). There are some varieties where other ingredients are added, such as shiitake mushrooms, niboshi (dried baby sardines), or iriko (dried anchovies).

Making dashi is very simple and quick. Here are the basic steps:
