To begin, blend the nibs, koji grains, and salt together with the water. Cacao nibs are very hard don't worry about getting it to a smooth paste – this coarse miso is meant to have a bit of texture to it
250g of cacao nibs
125g of dried koji rice
18g of salt
250ml of water
Transfer to a container and drop the container on the work surface a few times to get rid of any air bubbles – you need the carbon dioxide to escape otherwise it will not ferment correctly
Cover the container with muslin cloth (secured with string or elastic) and leave in a warm place – the warmer it is, the quicker the fermentation process will be. 25°C takes around 5 days, so it's best to make this in summer if you don’t have a dehydrator
Taste after 5 days. If you are happy with the flavour, store in the fridge to halt the fermentation process. If you are in no hurry, you can carry on fermenting for a deeper flavour
