This classic Bengali comfort dish is built entirely on pantry staples and fresh produce, making it a naturally plant-based recipe without any substitutions or workarounds. Soaked white poppy seeds are ground into a dense, fragrant paste that clings to every cube of golden potato — it's rich and nutty in a way that feels almost creamy, even though there's not a drop of dairy involved. Mustard oil does the heavy lifting here, bringing a pungent, slightly smoky depth that you simply can't replicate with a neutral cooking oil, and that final drizzle of raw mustard oil at the end keeps the flavor bright and alive. 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. The low-and-slow covered cook at the end is what makes this dish so satisfying — the posto paste thickens into a dry, clinging coating rather than a sauce, so every bite is intensely flavored all the way through. It's the kind of weeknight dinner that feels like it took far more effort than it actually did, and it pairs beautifully with steamed rice or flatbread.

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. 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.
