Puri — Water Content for Puffing (पूरी)

Puri appears in ancient Indian texts; its specific deep-frying technique is documented in Vedic cooking traditions and the Ayurvedic texts that describe the medicinal properties of wheat combined with ghee

Puri (पूरी) is the deep-fried unleavened wheat bread that puffs into a hollow, golden balloon — the opposite of roti in cooking method but from similar atta (whole wheat) dough. The puffing mechanism is entirely different from roti's flame-puffing: in puri, the water in the dough converts to steam inside the hot oil, expanding the dough from within; the sealed exterior sets rapidly as the gluten cooks, trapping the steam and producing the inflated sphere. Water content in the dough is the primary puffing variable — too little water produces dough that sets before sufficient steam is generated; too much water produces oil-absorbing, limp puris.

Puri served with aloo sabzi (potato curry) is India's quintessential festival meal — the combination of crisp, freshly fried bread with mildly spiced potato appears at every North Indian celebration from weddings to religious festivals. The puri's hollow interior, filled with a small amount of curry, is also the mechanism for pani puri (the hollow shell filled with spiced water).
