Soak the cashew nuts and nuts in plenty of water for 6 to 12 hours. Put in a sieve and rinse thoroughly under running water.
Puree the soaked nuts with coconut milk, cinnamon powder and honey or banana in a blender until an even, gritty pulp is formed.
If the porridge is too runny, cook it in a small saucepan until it has thickened sufficiently. It will also become even firmer in the refrigerator.
Enjoy hot or cold with the fresh berries or dried cranberries as desired.
When closed airtight in the refrigerator, the porridge can be kept for at least 2 - 3 days. However, if it was made with banana, it should be eaten the same day.
