Method :
Sieve the flour very well. Mix the sugar & yeast in 1 teacup of warm water and stir until the yeast dissolves. Cover and wait for 7-8 mins until the mixture is full of froth.

Add this liquid along with the curds, ghee and salt to the flour and make a soft dough by adding some more warm water.

Knead the dough for at least 7-8 mins. cover the dough with a wet cloth for 1/2 an hour. Knead again for 1 minute. Divide the dough into 20 small pieces and shape into naans.

Grease a pressure cooker very lightly with oil. Remove the lid from the pressure cooker and heat it upside down. Take each naan, apply a little water on one side and stick the wet side around the inside of the pressure cooker till brown spots appear. You can put 3 - 4 naans at a time in the pressure cooker.
