Dum Cooking — Sealed and Slow
Dum cooking is sealing a vessel and cooking over very low heat. The seal traps steam which continuously condenses and falls back into the dish — creating a self-basting, pressure-elevated cooking environment with concentrated aromatics.
Volatile aromatic compounds from saffron, kewra, cardamom cannot escape — they condense on the lid and fall back into food repeatedly. This is why dum-cooked biryani has its specific perfumed quality that dissipates the moment you open the lid.
1
Prepare vessel with tight seal
Heavy-bottomed pot with tight lid. Seal with dough (atta + water) or foil pressed firmly under heavy lid.
🔬 Dough seal is functional, not ceremonial — it expands when heated, creating a completely airtight seal.
2
Cook high 5 minutes then very low
Start on high to build pressure, then reduce to absolute minimum. Use tawa or heat diffuser between pot and flame.
🔬 Initial high heat builds steam environment. Subsequent very low heat maintains gentle circulation without burning base.
⚠ Without heat diffuser the base burns before top layers cook.
3
Never lift lid during cooking
Dum time: 20-30 min for biryani, 45-60 min for slow dal. No opening during cooking.
🔬 Opening releases concentrated aromatic steam — the perfume that defines dum cooking escapes immediately.
4
Rest 10 minutes before opening
After cooking, rest sealed 10 minutes before opening.
🔬 Steam redistributes evenly — pressure equalises and top layers absorb remaining aromatic steam.
