Soak the soya beans for 6 hours in cold water.
Place the soaked beans and water into a blender (I use the ninja). The ratio of soaked beans to water is 1:2 in volume. E.g. 1 cup of beans, 2 cups of water.
Grind to as fine as possible.
Sieve using a coffee sock.
Boil the milk with the pandan leaves.
When boiled, remove pandan leaves and leave to cool.
