Why don't my puris puff up?પૂરી ફૂલતી કેમ નથી?
A puri puffs because the moisture inside it flashes to steam in hot oil and has nowhere to escape, so pressure builds between the two layers of dough and lifts them apart like a balloon. Anything that lets that steam leak out, or that stops it forming fast enough, gives you a flat puri: soft dough, uneven rolling, or oil that is not hot enough.
What is going wrong
The dough was kneaded soft
A soft roti-style dough cannot hold the pressure. The layer stretches, goes slack, and the steam escapes before it can lift anything. Such puris stay flat and soak up oil, because oil moves easily into soft dough. If your finger leaves a dent that stays, the dough is too soft. Puri dough should be firm and push back against your thumb.
Rolled to an uneven thickness
Wherever the disc is thinner than the rest, the steam tears through and the pressure is gone in an instant. If one side lifts while the other stays flat, or you see little jets fizzing in the oil, the rolling was uneven. Roll from the centre outwards with even pressure so the whole disc is the same thickness, and resist thinning the edges.
Oil not hot enough
In cool oil the moisture turns to steam slowly, too slowly for pressure to build, and the puri sits at the bottom absorbing fat instead of rising. If it does not float up almost at once, or there is no ring of fine bubbles around it, the oil is not ready. Drop in a pea of dough to test: it should surface immediately rather than drifting up.
No press with the slotted spoon
As the puri goes in, it needs a gentle push down with the back of the slotted spoon. That press keeps the whole disc submerged in hot oil so both faces heat at the same time and the steam lifts the middle. Without it the puri floats, cooks only underneath, and stays flat. Keep the press light, though, because pushing hard splits the layer.
Rolled puris left standing too long
Discs left waiting dry out on the surface, and a dry skin cannot hold steam, while the dusting flour on them burns and darkens the oil. A chalky white look on the surface means they have dried. Roll and fry as you go, and if you must hold them, keep them stacked under a cloth.
What to do right now
If the puris are coming out flat, check the oil first, since a pea of dough should surface instantly. Then knead a little dry flour into the remaining dough to firm it up, and roll the next ones slightly smaller but evenly thick, pressing each one down gently with the slotted spoon as it goes in. The ones that already came out flat and greasy will not puff on a second frying. Break them up and eat them alongside the sabzi, or keep them for crisps in chaat.
Getting it right next time
- Knead firm, adding water a little at a time, then rest the dough covered for fifteen minutes.
- Roll with a smear of oil rather than dry flour so the frying oil stays clean.
- Keep the thickness even and do not roll the edges thinner than the middle.
- Wait until the oil is properly hot, and fry only two or three at a time.
- Press gently with the slotted spoon as each puri goes in, and turn it once it has puffed.

Does adding semolina to the dough help?
A spoon of fine semolina per bowl of flour makes puris crisper and keeps them crisp longer, but it is not what makes them puff. Firm dough, even rolling and hot oil do that. Too much semolina actually works against you, because the layer becomes crumbly and tears instead of inflating.
Why do my puris drink so much oil?
Nearly always cool oil or soft dough. In cool oil the surface does not set quickly, which gives the fat time to soak in. Frying too many at once has the same effect, since each cold disc drops the oil temperature. Let the oil come back up to heat between batches and keep the dough firm.
My puris deflate as they cool. Is that a problem?
No, that is normal. The steam inside condenses, the pressure goes, and the puri settles. What matters is that it should still be crisp once it has deflated, not soft and oily. If it is, the oil was too cool. Drain them on a rack rather than stacking them on a plate, because trapped steam softens the ones underneath.
