Why biryani behaves differently at scale
Biryani is a steaming dish, not a boiling one. Everything about scaling it is about controlling how much steam reaches the top of the pot and how long the bottom sits against direct heat. A recipe that works for four in a saucepan will produce a burnt base and raw upper rice in a catering pot if you simply multiply it.

- 1 tsp turmeric
- 2 tsp garam masala
- Juice of 1 lemon

Rice
- 900g aged basmati rice
- 4 green cardamom pods, 1 black cardamom, 1 cinnamon stick, 4 cloves, 2 bay leaves
- 2 tbsp salt
Layering
- 4 large onions, finely sliced and fried to deep gold (birista)

- A generous pinch of saffron soaked in 100ml warm milk
- 60g ghee
Method
- 1
Marinate
Combine the chicken with every marinade ingredient and half the fried onions. Cover and refrigerate for at least four hours, ideally overnight. This is the step that cannot be rushed or scaled away.

Soak and par-cook the rice
Rinse the basmati until the water runs clear, then soak for 30 minutes. Boil in heavily salted water with the whole spices for 4–5 minutes only — the grain should snap, not bend. Drain immediately and spread out to stop the cooking.

Build the layers
Spread the marinated chicken in a heavy-based pot. Cover with the par-cooked rice. Scatter the remaining fried onions, coriander and mint, then spoon over the saffron milk and dot with ghee.

Seal and cook on dum
Cover with foil and a tight lid. Cook on high heat for 5 minutes to build steam, then on the lowest possible heat for 35–40 minutes. Do not lift the lid.

Rest and fold
Rest sealed for 15 minutes off the heat. Fold gently from the bottom of the pot upwards with a flat spoon so the layers mix without breaking the grain.
Chef’s notes
- Scaling past about 12kg of rice, split into multiple pots rather than one deep one — the bottom layer overcooks long before the top steams through.
- Aged basmati is not a luxury here. New-crop rice collapses on dum.
- For a buffet, hold biryani in a covered chafing unit and fold it only once, immediately before service.
- Serve with a plain cucumber raita; the acidity is what makes the dish feel light at the end of a long menu.
