How a proper biryani takes eighteen hours: the case for the sealed pot

There is a quiet disagreement in most New York Indian kitchens about what a biryani actually is. On one side: a fragrant rice pilaf with some protein stirred through it, finished to order in twenty minutes. On the other side: a slow-cooked, layered, sealed-pot dish where the rice and the protein finish together, under their own steam, on the same heat. Both end up on menus labeled "biryani." Only the second one is, actually, a biryani.

We cook the second one. Here is what that day looks like.

10:00 AM — the lamb goes into yogurt

Bone-in lamb shank gets trimmed and cut into large pieces. Into a deep steel bowl with hung yogurt, garlic paste, ginger paste, toasted and ground whole spices (coriander, cumin, clove, cardamom, a stick of cinnamon, a piece of mace), fresh green chili, kashmiri chili powder, salt, and a hit of fresh lime. The marinade goes into the walk-in and stays there until service.

Six hours is the floor. Overnight is the goal.

3:00 PM — rice, parboiled with intent

Long-grain aged basmati is soaked in cool water for thirty minutes, then parboiled in a big pot of water spiked with whole spices, salt, and a splash of oil. Parboiled is the operative word — the grain should be cooked maybe seventy percent. You need a kernel with some bite, because it is going to finish on top of the lamb.

The rice drains onto a sheet pan and cools. If it cools too long it goes chalky. If it is still too hot when you layer, it overcooks during the dum. Timing is the whole game.

5:00 PM — the onion

Separately, we fry thinly-sliced onion in ghee until it is the color of dark honey. This is the barista — crucial, smoky, almost caramelized. Some goes into the layering. Some gets reserved for the top.

6:00 PM — the layering

A heavy-bottomed pot goes on the stove. The marinated lamb goes in first, with a little more ghee and a cup of the yogurt marinade. Then a layer of parboiled rice. Then fried onion, a handful of mint, a handful of cilantro, a spoon of rose water, and saffron milk — milk warmed with a few threads of saffron so it runs through the rice in streaks.

A second layer of lamb is unusual; most biryanis are just one layer up of protein, one big layer of rice on top. The finished pile comes up to maybe two inches below the rim.

7:00 PM — sealing the pot

The lid goes on, and we seal the gap between lid and pot with a rope of wheat dough. This is the dum. The pot goes on a low flame for forty to fifty minutes — sometimes longer for lamb — and from that point, nothing comes out and nothing goes in. The steam stays trapped. The rice finishes on the lamb's heat and the lamb's steam. Flavor travels both directions at once.

Open the pot too early and the rice is underdone. Open it too late and the bottom scorches. This is what people mean when they say biryani is a head cook's dish.

8:00 PM — cutting it open

We break the dough seal tableside when we can. The steam that comes out is — there is no other word for it — theatrical. Saffron-orange, meat-scented, with the bright bite of mint and green chili on the top. The spoon goes in sideways, all the way to the bottom of the pot, so you get rice and onion and lamb in the same lift. Served with a cool yogurt raita on the side to play against the heat.

Why we cannot do this on demand

This whole process is why a proper biryani is on our menu as a set dish, prepared each day in limited quantity. The pot is the pot. We cannot parboil the rice at six for a seven o'clock table — the seal has to go on an hour before service. We can do biryani a hundred ways, but we cannot do it faster than the process lets us.

If you want a biryani on a Friday night, the best thing you can do is order early. The second best thing is to understand why we do it this way. The third best thing is to eat it while the steam is still coming up.

You can find ours under Biryani on the menu — lamb, chicken, vegetable, and shrimp.
