Dum is not simply a word added to a menu name. It is a method built around trapped steam, controlled heat and patience. The technique gives rice time to absorb the aroma of the masala without turning heavy or losing the individuality of each grain.
The ingredients are prepared in layers
The protein or vegetables are seasoned separately from the rice. Aromatic basmati, slow-cooked masala, browned onions and whole spices are then arranged so flavour moves through the handi as it cooks.
The seal changes the cooking environment
Closing the handi keeps steam and aroma inside. On low heat, that steam finishes the rice and tenderises the layers below it. Opening the seal early releases the very fragrance the method is designed to protect.
Good dum biryani should not feel uniform
A proper serving has variation: some grains carry more saffron aroma, some sit closer to the masala and some remain lighter. Mixing the handi gently brings those layers together without crushing the rice.
Order the size that matches the table
A 650ml portion is intended for one person, while larger handis work for sharing. For parties, the complete menu matters: kebabs, gravies and dessert reduce the amount of biryani each guest is likely to take.
