- To make batter for idli let's soak rice and dal first. 
- Combine urad dal & methi seeds into a bowl. Wash and soak it in enough water for at least 8 hours. 
- In another bowl wash and soak rice in enough water for at least 8 hours. 
- Rinse and soak poha with water for about 30 mins before blending. 
- Grind to make batter 
- After 8 hours, drain the water from both the bowls. In a wet grinder jar, add soaked urad dal, methi, soaked poha, salt & water. 
- Blend all of them till thick and smooth consistency. The idli batter should not turn hot or even warm while blending as it makes idli dense. 
- Once done transfer this to a bowl and set aside for fermentation. 
- Next add soaked rice to the blender with water (mentioned in the ingredients). Grind to a little coarse batter like of semolina/sooji texture. 
- Mix this to the dal batter we grinded earlier. Mix both of them well with your hands. The batter must be thick yet be of dropping consistency. 
- Use your hands to mix as it helps to ferment faster and better. A little more water can be added, if you feel the batter is too thick.
