Question 9

Do puris puff better when made fresh or from stored dough? (Page 7)

Accepted Answer

Puris usually puff better when made from fresh dough rather than stored dough. Fresh dough has the right moisture and softness, which helps the puris puff up properly. Stored dough often becomes dry and hard, making it difficult for the puris to puff up well.
