This Bengali classic is pure comfort food — tender Yukon Gold potatoes coated in a thick, fragrant paste made from soaked and ground white poppy seeds, with heat from green chilies and a warm backbone of turmeric and nigella seeds. The technique is straightforward but deeply satisfying: you bloom whole spices in mustard oil, build a golden crust on the potatoes, then let everything braise together until the posto paste clings to every cube in a rich, dry coating. Mustard oil is the soul of this dish, used twice — once for cooking and once as a finishing drizzle — giving it that distinctly pungent, nutty depth that makes Bengali cooking so addictive. Every single ingredient here is naturally free of caffeine, so there's no need to audit labels or swap anything out. It's a one-pan dish that comes together with pantry staples and a spice grinder, making it genuinely weeknight-friendly despite how impressive it tastes. Serve it over steamed rice and let the paste do all the talking.

Ingredients

4 servings

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.
