This Bengali classic is pure comfort — golden potato cubes coated in a thick, fragrant paste made from soaked and ground white poppy seeds, bloomed in smoky mustard oil with nigella seeds and dried red chili. The flavor is earthy, subtly nutty, and gently spiced in a way that feels deeply satisfying without being loud or heavy. Because the entire dish is built from whole spices, fresh chilies, and pantry staples, there's nothing to second-guess when it comes to hidden fermented or leavened ingredients — it's naturally free of anything that would raise a flag. The technique matters here: smoking the mustard oil first mellows its sharpness, and letting the posto paste slowly thicken around the potatoes over low heat is what gives each piece that dense, clinging coating. A final drizzle of raw mustard oil right before serving adds a peppery lift that makes the whole dish pop. It's the kind of weeknight side that tastes like it took far more effort than it did, and it pairs beautifully with plain rice or flatbread.

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.
