This Bengali classic is pure comfort — tender Yukon Gold potatoes coated in a thick, fragrant paste of 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 the recipe, ground into a dense, opaque coating that clings to every cube of potato as it slowly steams and thickens in the pan. Nigella seeds and a dried red chili bloom in hot mustard oil at the start, building a deeply aromatic base before the potatoes even hit the skillet. Every ingredient here is straightforward and naturally plant-based, with no legume flours or hidden additives to navigate — just whole spices, potatoes, and that gorgeous posto paste doing all the work. The technique is patient but not complicated: a light sear on the potatoes, then a covered braise until they're completely tender and the paste has reduced to a dry, clinging coat. It's the kind of dish that tastes like it took far more effort than it did, and it pairs beautifully with steamed rice for a deeply satisfying meal.

For the posto paste

½ cup white poppy seeds (posto)
2 green chilies, roughly chopped
¼ tsp salt
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

For serving

1 green chili, slit lengthwise (optional)

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. Grind to a smooth, thick paste, scraping down the sides as needed and adding water 1 tsp at a time only if the blades stall. The paste should be dense and opaque, not watery.
