Wash the foxtail millet a couple of times until the water runs clear. Soak with enough water to cover it.
In another vessel, wash and soak the urad dal along with fenugreek seeds. Cover both vessels with a lid.
Let the soaking be done for at least four hours.
Once the soaking time is done, grind it in either grinder or a mixer jar.
I used a mixer jar, so first, take the drained urad dal and pulse it a couple of times.
Make sure the dal is all ground and leveled again.
Now sprinkle water over it and grind to a smooth soft batter.
Add as little water as possible. We only need it for getting ground well.
The batter texture should be like almost butter.
Now remove to a bowl, add the drained millet to the jar.
Again grind to a smooth paste. You will still find it to be a granular texture, add water and grind to a smooth paste as much as possible.
Now add this to urad dal paste, add salt, and beat it well.
Cover with a lid and let it ferment overnight or for at least 8 hours.
