  1. 1Instant dashi
    Follow the packet
    You lose some clarity; most are salted and have MSG — salt last.

    You lose the smoky bonito — but it's vegetarian, and very good.

Knowing it

Where to buy
Kombu and katsuobushi from Japanese grocers.
A little history
Umami itself was named from dashi: the chemist Kikunae Ikeda isolated glutamate from kombu in 1908.
Worth knowing
Never boil the kombu — it turns slimy and bitter.
