Step 1 of 6

Soak and grind

Soak the rice in one bowl and the urad dal with the fenugreek seeds in another for six hours, then drain and grind each to a smooth paste with a little fresh water, the dal first.

Grind the dal on its own and grind it long — it should go pale, light and frothy. That aeration is what lifts the batter.
