Preparation of poori One kilogram of wheat flour was taken. Water (600ml) was added and the mix was made into dough in a Hobart mixer (Hobart, England). The dough was made into ball (0.02 kg each), which was pressed between the two flat circular plates hinged at the periphery to form circular form of raw processed material and after frying is named as poori. The average diameter and thickness of the poori before frying were 0.08m and 0.002m, respectively. These parameters after frying increased to 0.085m and 0.003m, respectively.
