The works


A bundle of all our secrets for you to experiment (and impress).


The Way

KOJI IS A MYSTERIOUS THING, traditionally used to make soy sauce and miso.


We have harnessed its powers in our secret recipe to unleash the bold flavours in your best dishes!

2 Doctors
Changing Food

We are Koji Kins - Two doctors, nutritional scientists and Koji cultivators making food healthy and delicious.


Since discovering Koji we have loved using it to diversify classic dishes and extract the most flavour and quality from ingredients.


With Great Taste Awards in the pocket, we are planning big things for helping the UK elevate their dishes in a green and clean way. Every dish is special and we’re here to elevate cooking, naturally.

What does koji do?

Koji breaks protein up and releases flavour, like browning a steak or roasting an aubergine!

Our koji tonics bring bold flavour out of foraged mushrooms, adding depth to your dishes. They’re perfect in everything from a morning toastie to your flashy dinner-party show-off course… 

Our products are all naturally fermented, made from 100% plant-based ingredients with known prebiotic properties that contain no gluten.

Supercharge your dishes, like some of your favourite Michelin-starred chefs. Just don’t tell anyone.
