While toor dal is cooking, start making dhokli dough.
In a wide bowl, take all dough ingredients listed above except water and mix it well.
Start adding little water at a time and kneed the dough. Usually 2 cups of flour takes one cup of water to make a soft dough. Once the dough is formed, add 2 tbsp of peanut oil and kneed it for a minute or two. It makes the dough softer and smoother. Cover it and keep it aside for 10-15 minutes.
Make 8 even dough balls for the dhokli.
Roll each dough ball with the help of dry flour like wheat flour or rice flour.
Make 10" to 12" big rotis. It should not be too thick.
Cook rolled roties on a big flat tawa for 10 seconds on each side. This step is unusual for dhokli recipe. But I like to partially cook dhoklis before I add them to the dal. It helps dhokli not stick together when you add it to the boiling dal and it does not lump up together.
Roll all 8 rotis and partially cook them.
Once all the rotis are rolled and cooked. Cut them into diamond shapes using either kitchen shears, knife or pizza cutter. Cover cut dhoklis and keep them aside
