It is much simpler than you think!
To make just under 1 litre of soy milk: Wash and crack 125g soya beans. Remove hulls and soak the beans in water for 6-8 hours. Process them in a blender with 1 litre of fresh water and strain through muslin. Collect the milk into a saucepan and boil for 5 minutes. Cool and store up to 3 days in the fridge.
