Heat & Cooking Methods
Dum
Also: dam, dum pukht, dam pukht, slow steam cooking
A South Asian slow-steam technique in which food cooks sealed inside a pot, trapping moisture and aromatics to build layered depth.
/dum (rhymes with 'room' in Urdu/Hindi)/Persian and Urdu: 'dam' (دم), meaning breath, air, or steam. Entered Mughal court cuisine in the 16th–17th century, codified in the Awadhi kitchens of Lucknow.
Definition
Dum (from the Persian and Urdu word meaning 'breath' or 'steam') is a cooking method in which a pot is hermetically sealed — traditionally with a rope of stiff dough called 'atta loi', though foil or a tight-fitting lid weighted with coals is also used — and set over very low heat. The trapped steam circulates within the vessel, cooking food gently and evenly from all sides. Simultaneously, heat is sometimes applied from above (using live coals placed on the lid) so the food cooks in a top-down and bottom-up thermal embrace. The technique is the foundation of dum biryani, where parcooked rice and spiced meat are sealed together so that each grain absorbs the perfumed steam rising from the layer below. Dum pukht, literally 'to stifle in steam', is the full name of the classical Awadhi culinary tradition built almost entirely around this method. In Levantine cooking, a related concept appears in clay-pot preparations sealed with flatbread. The defining qualities of dum-cooked food are an extraordinarily tender texture, concentrated aromatics (since volatile compounds cannot escape), and a mellow, blended depth of spicing that sharp, high-heat methods cannot replicate.
In use
“After layering the parcooked rice over the spiced lamb, the chef sealed the handi with a thick atta rope and let it cook on dum for forty-five minutes over a tawa on the lowest flame.”

Notes
Dough seal vs. foil
The traditional atta loi seal is not merely practical — it signals ceremony and prevents curious cooks from lifting the lid. Many restaurants now use foil crimped tightly around the rim, which is functionally identical but lacks the theatrics. When the dough seal is broken at table, the first billow of saffron-and-rose-water steam is part of the experience.
Heat source above and below
Authentic dum often places live charcoal on top of the lid, creating a tandoor-like enclosure. This 'do-anga' (two-heat) method ensures the rice on the upper layers cooks at the same rate as those near the base, preventing the bottom from burning while the top stays undercooked.
