To prepare the powder mix :
1) Soak the jowar for about 8 hours or overnight. Drain thoroughly and leave to air dry for some time
2) In a dry pan, roast the grains. Put the lid on and keep shaking the pan. Some of the grains may start to pop. Roast until all the moisture has evaporated and there is no more popping sound. Let it cool.
3) Powder the roasted grains into a fine powder in your blender.
4) Mix with the ground peanuts if using and store at room temperature in an airtight container
To prepare the cereal.
Mix 2-3 tablespoons of the powder in a cup of liquid and cook for about 3-4 minutes while whisking continuously until you get a smooth porridge. Adjust powder and liquid according to preference and add sweetener or salt as appropriate. Serve warm.
