Meanwhile make the dough with maida.
In a wide mixing bowl add maida and a pinch of salt.
Add little water and make soft dough.
Add 1 tbsp oil and knead the dough well.
Add 2 or 3 tbsp oil and cover the dough to rest.

If it is more than that also it would be fine.
Let the dough rest as much as time as possible to get soft and thin obbattu.
Add 1 cup water to the soaked chana dal and pressure cook it for 3 to 5 whistles.
Let the cooker cool down completely, mash the dal.
If any excess water found just drain it before mashing.

The dal dough should leave the cooker bottom and turn into a single mass.
