Equipment & Vessel Techniques

Lagan

Also: lagan deg, lagan ki deg

A heavy, wide, flat-bottomed brass or copper vessel central to North Indian dum cooking and slow braises, prized for its thermal mass and even heat distribution.

Urdu / Hindustani; from Persian lagan (لگن), meaning a wide basin or trough. The vessel and its name entered the cuisine of North India through the Mughal court kitchens of Lucknow and Delhi.

Definition

The lagan is a traditional cooking vessel of the Indian subcontinent, characteristically wide and shallow with a flat base and straight or gently flared sides. Made from heavy-gauge tinned brass or copper — though modern versions in thick-gauge stainless steel or anodized aluminum exist — it is the canonical vessel for dum pukht, the sealed slow-cooking technique central to Awadhi and Mughal court cuisine. Its defining feature is thermal mass: the thick walls and broad base absorb heat slowly and release it with extraordinary uniformity, eliminating hot spots that would scorch a delicate biryani or a lamb roghan josh. When used for dum cooking, the lagan's wide rim is sealed with a rope of atta dough (or a tight-fitting lid weighted with charcoal embers) to trap all aromatic steam inside the pot, creating an internal pressure environment that tenderizes meat and perfumes every grain of rice. The flat bottom sits flush on a low, smoldering heat source — traditionally a wood-fired chulha or a bed of glowing coals — ensuring gentle, enveloping heat rather than concentrated bottom-up scorching. Size is significant: a lagan is always proportioned generously, because the depth of the ingredient bed relative to the vessel diameter affects condensation patterns and moisture recycling during the dum phase.

In use

“The head khansama lowered the sealed lagan onto a ring of embers, pressing a second layer of hot coals onto its lid, so the biryani would dum for a full forty minutes from both above and below.”

Notes

Heat management from above and below

Authentic dum cooking uses the lagan as a two-directional oven: hot coals on the lid and a slow flame beneath. This technique, called dum dena, means the food never experiences direct bottom heat intense enough to create a crust — it cooks in a perfumed steam chamber. Modern adaptations use a tawa (flat griddle) placed between the lagan and the stovetop burner to diffuse direct flame, approximating the ember-smoldering effect.

Vessel vs. technique confusion

In contemporary restaurant kitchens, 'lagan' is often used loosely to describe the sealed-pot technique rather than the vessel specifically. Purists distinguish between the lagan (vessel), the handi (a deeper, rounded-base pot), and the deg (the largest cauldron used for communal or wedding-scale cooking). Each suits a different depth-to-diameter ratio and thus a different category of dish.
