This Bengali classic is pure comfort — 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 undercurrent of turmeric and nigella seeds running through every bite. The poppy seed paste, known as posto, is the soul of the dish: dense, opaque, and deeply savory in a way that feels almost creamy without a drop of dairy. Mustard oil does serious heavy lifting here, first bloomed until it loses its raw sharpness, then finished raw as a drizzle at the end for that signature pungent brightness that makes Bengali cooking so distinctive. Every ingredient in this recipe is naturally plant-based and free from tree nuts of any kind, so there's no need to scrutinize labels or worry about hidden additions sneaking in. The technique is straightforward — soak, grind, bloom, coat, and simmer — but the result tastes like something that took far more effort than it did. It's the kind of weeknight dish that quietly becomes a household staple, especially good alongside steamed rice when you want something deeply satisfying without a lot of fuss.

Place the white poppy seeds in a small bowl, cover with cold water, and soak for 30 minutes. Drain well.
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.
