Making your own raw oat flour
  1. Soak your raw oat groats for 8 hours or overnight in a bowl, covering them with cold water and adding a teaspoon of lemon juice. The oat groats will swell up overnight and absorb the water.
  2. After soaking, rinse the oat groats well under cold running water.
  3. Turn the soaked oats onto a teflex dehydrator sheet and dehydrate at 115 degree F for 24hours until dry. This should take about 24 hours.
  4. When dry, whizz them in the blender to form a powder.
  5. Sieve the powdered oats to collect the ‘flour’ and discard the husks.
