Kolkata biryani: the potato, the perfume, and how to order it

Overview

Biryani is cooked all over India, and almost everywhere it is a loud dish — deep with fried onion, heavy with spice, stained a bright orange. Kolkata’s is the quiet one. The rice is pale, close to off-white, scented rather than fired, and the whole plate leans on fragrance where other styles lean on heat. It is the most restrained biryani in the country, and that restraint is the point of it.

Two things on the plate are unmistakably local. One is a whole potato, boiled soft and soaked through with the same saffron-and-spice liquor as the rice — not a bit of potato, a whole one, and its absence is enough to tell you the kitchen is cooking someone else’s biryani. The other, on most plates, is a hard-boiled egg. Between them they are the signature, and a Kolkata cook will not leave either out.

The history behind it is real, and worth telling straight because so much food history isn’t. In 1856 the British deposed Wajid Ali Shah, the last Nawab of Awadh, and exiled him from Lucknow to Metiabruz, then a settlement on the southern edge of the city. He brought his court, and with it his kitchen, and the Awadhi biryani his cooks made slowly took on a Bengali accent — gentler spicing, the local taste for the subtle over the fierce. That lineage is documented; the city’s biryani genuinely descends from a court in exile.

The potato is where fact shades into folklore. The most repeated story is that the Nawab’s income shrank in exile and his cooks stretched costly meat with potato, then still something of a novelty in Bengal. It is a good story and it may be broadly true, but the detail is not firmly documented and you will hear it told with a confidence the evidence does not support. What is not in doubt is that the potato stayed, long after any need to economise, and became the thing people now come for.

What to order

You order by the meat, and the rest comes with it.

• mutton biryani — the original and the one to have. Goat meat, on the bone, cooked until it gives. This is the version the whole tradition is built around.
• chicken biryani — lighter, cheaper, quicker to sell out of at a busy counter. Good, but a step down from mutton in a dish that was made for mutton.
• egg biryani — the meatless-but-not-vegetarian option, built around the boiled egg and the potato. Cheaper again, and a genuine order rather than a consolation.

Whatever the meat, the potato and the egg should already be in the plate, not charged as extras — that is how the dish is defined here, and a counter that itemises them is telling you something about itself. If they ask whether you want aloo (potato) and dim (egg), the answer is yes to both; leaving them off is the tourist’s order, not the local’s.

The classic thing to eat alongside it is chaap — a rich, slow-cooked mutton cutlet in a thick, mildly sweet gravy, ordered as a side and eaten with the rice. A plate of biryani with a chaap on the side is the full local meal, and asking for it that way is the closest thing to ordering like a regular.

One honest note on the rice: it is meant to be gentle. If you arrive expecting the fire of a southern biryani you may find this one tame. That is not the kitchen underseasoning — it is the dish, and turning up the heat would make it a different one.

What to avoid

The failure to spot is a biryani wearing this city’s name while cooking another city’s recipe. The clearest tell is colour: if the rice is a uniform, lurid orange or red, it has been dyed, and a heavily dyed biryani is almost never the restrained Kolkata style. The real thing is pale and patchy, a few grains touched with saffron rather than the whole pot painted.

The second tell is the missing potato. A plate that arrives with no potato at all, or with the potato sold back to you as a paid add-on, is either not the local style or a place that has decided its customers won’t know the difference. In a city where the potato is the signature, leaving it out is not a small liberty.

Be wary, too, of the counter that sells a dozen kinds of biryani in bright English on a board — “special”, “supreme”, “royal” and so on. The dish here is defined by meat and by restraint, not by a menu of grades, and a long ladder of premium names is usually about margin rather than about the pot. A place doing this one thing well tends to advertise it plainly, if at all.

And treat “Hyderabadi” or “Awadhi” biryani sold under a Kolkata sign as what it says it is: a different regional style, often good, but not the local dish. Ordering it is no mistake; mistaking it for the Kolkata version is.

Practicalities

A plate of mutton biryani in an ordinary biryani house runs roughly €2 to €4, with chicken a euro or so less and egg cheaper again; a chaap on the side adds a little more. A price far below that range usually means a smaller portion or chicken standing in for mutton, and one well above it, in an ordinary neighbourhood, is charging for its frontage rather than its pot.

It is a full meal, eaten at lunch and dinner rather than snacked on, and the best plates come from places that cook biryani and little else — a deep vessel brought out and served down through its layers, so the meat and the soaked potato from the middle appear as the pot gets lower. The practical consequence: the popular counters can sell out of the good middle by late evening, and mutton goes before chicken, so it rewards not arriving last. Midday and early evening are the safe windows.

The bigger, established biryani houses take cards without fuss, but the smaller specialist counters can still be cash-first, so carry some. And eat it soon after it is served: the rice is at its most fragrant hot, and a Kolkata biryani left to go cold loses the very perfume that is the whole reason to choose this one over any other.
