Garum & Koji

Have you ever heard of Garum?

Garum is an ancient fermented fish sauce origins back to Roman period. It is really tasty, flavorful and umami-rich “exquisite liquid”, but it also has strong smell of fish.

Garum was originally made of sardines and mackerels, fermented with salt and its guts. This is why the original garum has an acquired smell and flavour.
However, Noma, the award-winning Copenhagen restaurant, twisted the idea of garum fermentation. They were aware of the versatility of koji that does the job for making garum without strong flavour instead of using fish guts.

A part from garum, Noma serves many dishes fermented with koji, their alternative idea of culinary explore influences numbers of chef and foodies in the world!
