This Bengali classic is pure comfort food — tender Yukon Gold potatoes coated in a thick, fragrant paste made from soaked white poppy seeds and green chilies, finished with a drizzle of raw mustard oil that gives the whole dish a distinctive, pungent warmth. The poppy seed paste is the soul of this recipe, grinding down into something dense and opaque that clings to every cube of potato in the most satisfying way. Nigella seeds and a dried red chili bloom in hot mustard oil at the start, building a spiced base that makes the kitchen smell incredible before the potatoes even hit the pan. Tree nut concerns are completely off the table here — every ingredient is straightforward and plant-based, from the spices to the finishing oil, with no hidden additions to second-guess. The technique is simple but deliberate: lightly golden potatoes first, then the posto paste stirred in with just enough water to steam everything tender before the lid comes off and the coating tightens into something almost dry and intensely flavored. It's the kind of dish that tastes deeply traditional because it is, and it pairs beautifully with steamed rice for a meal that feels both humble and special.

3 tbsp water, plus more as needed

For the aloo

1.5 lb (about 4 medium) yukon gold potatoes, peeled and cut into ¾-inch cubes
3 tbsp mustard oil
½ tsp nigella seeds (kalonji)
1 dried red chili
½ tsp turmeric
¾ tsp salt, or to taste
¼ cup water
1 tsp raw mustard oil, for finishing

Instructions

1
Place the white poppy seeds in a small bowl, cover with cold water, and soak for 30 minutes. Drain well.
2
Transfer the drained poppy seeds to a spice grinder or blender along with the 2 roughly chopped green chilies, 1/4 tsp salt, and 3 tbsp water.
