Heavy-Duty Aluminum Biryani Bagona Degh, 18 to 35 Liters

A bagona — bhagona, deg, degh, whichever spelling your supplier uses — is the deep aluminium pot a biryani kitchen seals and leaves alone. Narrow at the mouth, wide at the base, thick-bottomed, and sized in litres rather than quarts because that is how the trade buys them. Four sizes, from 18 to 35 litres.

What the shape is for

Dum cooking is about steam that cannot escape. Rice and meat go in layered, the lid goes on, the seam is sealed, and the pot sits on a low flame until it is done. A narrow mouth over a wide base means the steam that rises off the base hits the shoulder of the pot and falls back through the layers instead of venting. That recirculation is what leaves the grains separate and the meat tender without anyone lifting a lid to check.

It is the opposite geometry to a lagan, which is wide and open and cooks by base contact rather than trapped steam. Neither replaces the other. Kitchens working Delhi or Lucknowi style reach for a deg; Hyderabadi layering wants the lagan.

Sizes

Measure the bottom diameter against your burner before ordering, not the mouth. A deg only cooks evenly if the base is fully over the flame, and at 20.5 inches the #36 needs a proper range burner rather than a domestic hob.

Build

• Extra heavy duty aluminium throughout, with a thick base that holds a low steady heat without scorching the bottom layer.
• Thick enough not to crack or warp under daily commercial heat — warping is what finishes a cheap deg, because a base that no longer sits flat cooks unevenly for the rest of its life.
• Aluminium heats fast and holds heat well, which is why it is the traditional material for this pot rather than steel: less fuel to reach dum temperature, and a gentler fall-off when the flame goes down.

Beyond biryani

The same pot makes veg and non-veg pulao, and it is what most kitchens use for the large batches of rice they need on a catering day. Anything that wants long gentle heat and no stirring suits it.

Cleaning

Hand wash with warm water, mild soap and a soft sponge — aluminium is not dishwasher safe, and dishwasher detergent will dull and pit it. Dry straight away rather than letting it air dry, which is what causes limescale marking. Cooked-on residue lifts after a few minutes of simmering water with a splash of vinegar.
