Okara (left over in the process of soya milk making)
To dry okara, just spread okara homogeneously on a oven tray.
Let it dry in the oven at 50°C/100°F for two to three hours.
From time to time stir the okara so that it’ll dry homogeneously.
Store in a air-tight box.
Storage: dried okara can be kept for one year.
