At times due to the temperature difference in your place, the dough might not proof as you need. As we know the proofing activity is happening with the action of yeast and temperature plays a major role too. Hence despite the temperature difference and the moisture in the air, Instant Pot provides even proofing. Also without any doubt, the raising or Proofing is important in the flavor and texture of the bread. Hence I highly recommend proofing the dough in Instant Pot for your Naan bread.
