Method

1. About Kala Chana Chaat: This is one of the healthiest and most loved street foods in Bihar — earthy black chickpeas tossed with raw mango, chilli and tangy chaat spices. Sold at every dhaba, market stall and railway platform across the state, it is high in protein and fibre and makes a satisfying breakfast, snack or light meal.
2. Soak the kala chana overnight: Take 1 cup dried black chickpeas (kala chana). Pick over for any small stones or shrivelled beans. Wash thoroughly in 3-4 changes of water. Cover with plenty of cold water and soak for at least 8 hours or overnight; they will roughly double in size.
3. Drain and pressure cook: Drain the soaked chickpeas and place in a pressure cooker with 2 cups fresh water and 1/2 tsp salt. Cook on high heat for 4-5 whistles, then on low heat for 5 more minutes. If using a regular pot, simmer for 60-75 minutes until tender. The chickpeas should be soft enough to crush gently between thumb and finger but still hold their shape.
4. Drain and keep warm: Drain the cooked chickpeas, but reserve the cooking liquid (called aquafaba) — it can be used for soups or discarded. The chickpeas should still be warm when you assemble the chaat; warm chickpeas absorb the seasoning better than cold.
5. Choose a sour raw mango: Use a firm, hard, completely raw green mango — the skin should be bright green with no yellow spots. Press it; it should feel rock hard. A semi-ripe mango will turn the chaat sweet, which is not what you want.
6. Dice the raw mango: Wear gloves if your skin is sensitive — raw mango can cause itching for some people. Peel with a sturdy peeler. Cut the flesh away from the stone and finely dice into 5mm pieces. You need about 1/2 cup of diced raw mango.
7. Prepare the onion and chilli: Take 1 small red onion. Peel and chop into very fine 5mm dice. Take 2 fresh green chillies. Slit lengthwise and slice into thin rounds. Remove the seeds first if you prefer milder heat.
8. Dry-roast the cumin: This step makes a big difference. Take 1 tbsp whole cumin seeds in a small dry pan over medium heat. Toast for 90 seconds, shaking the pan often, until the seeds darken a shade and smell deeply nutty. Cool and grind in a mortar to a coarse powder. Use 1 tsp for the chaat and store the rest.
9. Understand chaat seasonings: Black salt (kala namak) is a sulphur-tinged salt sold at all Indian groceries — it is dark pink-grey despite the name. Tamarind paste (imli) gives the sour-sweet base. Both are essential and not interchangeable with regular salt or lemon.
10. Combine everything in a wide bowl: Place the warm drained chickpeas in a wide mixing bowl. Add the diced raw mango, chopped onion and sliced green chilli on top. A wide bowl lets you toss without crushing the chickpeas.
11. Add the spices: Sprinkle in 1 tsp roasted cumin powder, 1/2 tsp red chilli powder and 1/2 tsp black salt. Add 1 tsp tamarind paste and squeeze the juice of half a lemon. Add regular salt to taste — start with just a pinch, since the black salt and chaat masala already provide salinity.
12. Toss gently: Use two large spoons or your clean hands. Lift from the bottom and turn over gently 5-6 times until everything is evenly coated and the dressing has reached every chickpea. Do not stir aggressively or the mango pieces break down.
13. Taste and adjust: Dip a clean spoon and taste. The chaat should hit you with three flavours at once — tangy, spicy and earthy. Adjust lemon, salt or chilli to your liking.
14. Garnish and serve: Scatter 2 tbsp finely chopped fresh coriander over the top. Serve warm or at room temperature in small bowls or paper cones for that authentic street-food experience. Eat within 30 minutes for the best texture; longer than that and the mango softens and the chaat becomes watery.
