This classic Bengali potato dish is deeply comforting — tender Yukon Gold cubes coated in a thick, nutty paste made from soaked and ground white poppy seeds, bloomed in pungent mustard oil with nigella seeds and dried red chili. The result is earthy, subtly spicy, and unlike anything in the average weeknight rotation. Aloo posto is one of those dishes that sounds simple but delivers layers of flavor that feel genuinely special. The technique of smoking the mustard oil before adding the aromatics is a small step that makes a huge difference, rounding out the sharpness and giving the whole dish a warm, toasty depth. Because every ingredient here is whole and plant-based — potatoes, spices, poppy seeds, oil — there is nothing hidden to worry about, making it a clean and confident choice for anyone avoiding fungi or fungal-derived additives. The finishing drizzle of raw mustard oil right before serving adds a bright, peppery kick that ties everything together. Serve it simply with rice or flatbread and let the posto do all the talking.

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.
