Why chaat belongs on your table

Walk through any bustling bazaar in Sylhet or Dhaka and you'll hear the unmistakable clatter of a chaat wallah's metal bowls. He's layering crisp puris with soft potatoes, cold yoghurt and a glossy tamarind sauce that makes your mouth water before you've even taken a bite. Chaat is the great equaliser of South Asian street food — cheap, fast, endlessly adaptable and utterly addictive. For British cooks, it's also one of the most forgiving dishes you can make at home. There's no precise cooking to master, no tricky pastry to fold. It's about balance: something crisp, something soft, something cool and something sharp, all brought together with a tangy tamarind sauce that cuts through the richness.

In Bangladeshi and Sylheti households, chaat often appears at Eid gatherings, after Friday prayers or as a speedy Iftar opener. The version I'm sharing here is street-style in spirit — built in layers, served in little bowls or on paper plates, and eaten with a spoon or, better still, with your fingers.

The building blocks: puris, potatoes and chickpeas

Start with the puris. You can buy ready-made crisp puris from most Asian grocers in the UK — look for the small, disc-shaped ones in the snack aisle. If you'd rather make them, a simple dough of plain flour, a pinch of salt, a tablespoon of oil and enough water to bring it together will do. Roll into thin discs and deep-fry until they puff and turn golden. They keep for a week in an airtight tin, so make a batch and thank yourself later.

For the potatoes, boil 400g of waxy potatoes until tender, then peel and cube them while still warm. Dress them immediately with a teaspoon of roasted cumin powder, half a teaspoon of red chilli powder, a good pinch of salt and a squeeze of lemon. The warmth helps the spices cling. Set aside to cool.

Chickpeas come next. A 400g tin of chickpeas, drained and rinsed, is perfectly good. Toss them with a little salt, a pinch of chaat masala and a drizzle of mustard oil if you have it — the pungency is very Sylheti. If you're cooking dried chickpeas from scratch, soak 150g overnight, boil until soft, and season the same way.

The tangy tamarind sauce that makes it sing

This is the heart of the dish. You need 100g of tamarind pulp — either block tamarind soaked in 200ml of hot water and pressed through a sieve, or ready-made tamarind concentrate. Warm the pulp in a small pan with 2 tablespoons of jaggery or soft brown sugar, half a teaspoon of roasted cumin, a quarter teaspoon of black salt and a pinch of red chilli. Simmer for five minutes until it thickens to a pourable syrup. Taste it: it should be sour first, sweet second, with a savoury hum underneath. Let it cool completely.

While you're at it, whisk 200g of full-fat yoghurt with a tablespoon of water, a pinch of salt and a teaspoon of sugar until it's smooth and drizzle-able. You'll also want a green chutney — blitz a handful of coriander, a green chilli, a garlic clove, a squeeze of lemon and a pinch of salt with a splash of water. These three sauces are your toolkit.

Layering and serving, street-style

Now assemble. Crush four or five puris into the bottom of a bowl — don't be gentle, you want shards and crumbs. Spoon over a generous helping of the spiced potatoes, then a heap of chickpeas. Drizzle with the tamarind sauce, then the yoghurt, then the green chutney. Finish with a shower of fine sev (crispy gram flour noodles), a sprinkle of chopped red onion, fresh coriander and a dusting of chaat masala.

The order matters more than you'd think. Sauces go on in thin streams so every mouthful gets a bit of everything. If you're serving a crowd, set out the components in bowls and let people build their own — it's half the fun.

Sylheti twists and practical notes

Sylheti cooks often add a spoonful of hot chickpea curry or a little boiled egg to make chaat more substantial. Some families swap the yoghurt for a thin, salted lassi. A scattering of roasted peanuts or a few pomegranate seeds adds crunch and colour. In Bangladesh, you'll sometimes find doi bora — lentil dumplings soaked in yoghurt — folded through, which turns a snack into a proper meal.

A few practical points. Make the tamarind sauce up to a week ahead; it keeps beautifully in a jar in the fridge. Puris stay crisp for days if the tin is sealed. Potatoes and chickpeas can be prepped the morning of your gathering. What you cannot do ahead is assemble — chaat waits for no one. Build it just before serving, or the puris will go soggy and you'll lose the whole point of the dish.

Serve with cold drinks, plenty of napkins and no ceremony whatsoever. That's how it's done on the street, and that's how it tastes best at home.
