Koji - What is it and how to use it?

Koji can be found in most Japanese dishes and is raved about by many chefs and home cooks here in the UK. Koji is cooked rice that is put through a fermentation process that creates mould (don’t worry, it’s totally edible and takes your dishes to a whole new level of flavour). This mould thrives in a humid environment, which is why Koji is so prominent in Japanese cuisine. 

Koji creates an umami flavouring with a hint of sweetness through producing digestive enzymes. Koji produces the same flavourings as MSG and is often used as a natural alternative as it doesn’t have any additives. 

How To Use Koji

Koji in its original form is pretty simple, but it can come in a few different forms, meaning you can add it to literally anything you want, marinating meat, adding it to miso soup or even a spoonful on a morning if you really fancied it (wouldn't be our first recommendation). A recipe that is a must try is our Japanese Cream Stew With Koji - a proper winter warmer! 

 

If you’re looking to add more umami flavouring to your food here are some products that can help.

The best-kept secret that every home chef should have in their cupboard. This liquid shio Koji is ideal for stock and marinating meats and vegetables. The enzymes break down the proteins in meat and fish making them tender and giving a fully-flavoured finish.
