You'll need: Stovetop.

Includes soaking time.

Method

Drain the soaked poppy seeds. In a small blender, process the poppy seeds, a portion of the green chillies, and a splash of water into a remarkably smooth, thick paste.
Heat mustard oil in a kadhai on medium heat until it smokes lightly, neutralizing its raw pungency. Lower the heat.
Introduce the nigella seeds (kalonji) and the remaining slit green chillies. Sauté rapidly to temper the fat.
Add the potato cubes. Fry them on medium heat for 5-7 minutes until they develop light, golden-brown blisters.
5–7 min
Incorporate the turmeric powder (if utilizing) and salt. Toss the potatoes to coat them evenly.
Fold in the freshly ground poppy seed paste and cook the potatoes in it for 2-3 minutes. Do not let the posto over-fry, or it turns bitter.
2–3 min
Pour in the measured warm water and add the sugar. Bring the gravy to a gentle, sustained simmer.
Cover the pan and cook on low heat for 10-12 minutes until the potatoes yield completely to the touch and the gravy reduces to tightly coat the chunks.
10–12 min
Turn off the heat. Drizzle a few drops of raw mustard oil over the top for a classic, authentic punch, and serve hot.

How to tell it's done

Ultra-soft, buttery potatoes enveloped completely in a rich, clinging, inherently nutty, and slightly gritty white poppy seed reduction.

Getting it right

Tip

For a structurally perfect posto paste, ensure you use warm water for soaking. A traditional sil-batta (stone grinder) yields the best texture, but a high-powered mixer works beautifully.
