This classic Bengali potato dish is deeply comforting — golden-edged Yukon Gold cubes coated in a thick, nutty poppy seed paste that clings to every piece. The posto paste is the soul of the dish, made by soaking and grinding white poppy seeds with green chilies into a dense, opaque mixture that turns silky and rich as it cooks down with the potatoes. Mustard oil does serious heavy lifting here, giving the whole dish a pungent, slightly smoky backbone that you simply cannot replicate with a neutral cooking oil. Nigella seeds and a dried red chili bloom in the hot oil first, layering in a subtle bitterness and heat before the potatoes ever hit the pan. For anyone navigating a legume-free lifestyle, this recipe is a natural fit — every single ingredient is a whole spice, a vegetable, or an oil, with zero beans, lentils, or pulses anywhere in sight. The final drizzle of raw mustard oil right before serving is a small step that makes a noticeable difference, brightening the flavors and adding that unmistakable sharp finish that Bengali cooks swear by. It's the kind of dish that tastes like it took far more effort than it actually did.

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

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.
