Heat the oil and bloom the nigella seeds.
Heat mustard oil in a kadai over medium heat until it reaches a light smoking point, then lower the heat. Add nigella seeds and let them sizzle for a few seconds.
TIPHeating mustard oil well first softens its sharp raw taste. - saute · ~4 min

Cover and cook the bhaji.
Cover the kadai and cook on low heat for 10 to 12 minutes, stirring once or twice. The bottle gourd and pumpkin will release enough moisture to soften the vegetables and help them cook down.
TIPIf the pan looks dry too early, sprinkle in 1 to 2 tbsp water from your measured cooking water before covering again. - saute · ~4 min
Cook until soft and lightly mashed.
Uncover and cook for 3 to 4 minutes more, stirring gently and pressing a few pumpkin pieces into the lau. The bhaji should look soft, moist, and semi-dry.

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Cut the lau, kumro, and potato into similarly small cubes so they soften together without turning patchy.
- 2Let the mustard oil reach a light smoke before tempering; this keeps the bhaji fragrant without a raw pungent bite.
- 3Do not add much water early on, because bottle gourd releases plenty and too much liquid makes the bhaji watery.
- 4Gently mash a few pumpkin cubes at the end to naturally thicken the moisture and give the bhaji its soft Bengali texture.
- 5Keep the heat low while covered so the vegetables steam in their own juices instead of catching at the bottom.
- 6This bhaji tastes even better after 15 to 20 minutes of resting, when the sweetness and nigella flavor settle in.
- 7Store leftovers in the fridge and reheat uncovered on low heat to drive off extra moisture before serving with rice or roti.
Adapt it for your goals.
