Posto — poppy seed paste — is one of the most Bengali things that exists. Creamy, nutty, deeply comforting. Combined with jhinge (ridge gourd) and potato, tempered in mustard oil with kalo jeere, this is the kind of dish that makes you close your eyes when you eat it. Simple. Perfect. Irreplaceable.
"A tiny spoon of raw mustard oil at the end. That rawness — it adds so much."
— Baba's Saying
Ingredients — The Base
2 medium potatoes, cubed
2 long jhinge (ridge gourd), chopped
1 mutho (fistful) posto (poppy seeds)
2–3 green chillies (for soaking)
Water (for soaking & gravy)
Kalo jeere (nigella seeds)
2–3 slit green chillies (for tempering)
Mustard oil
A pinch of sugar
Salt to taste
✦ Optional upgrades (Baba's tips)
A few cashews (soaked with posto)
Fried onion (kept aside, added on top)
Raw mustard oil (finishing drizzle)
Method
- Soak the posto (poppy seeds) with 2–3 green chillies in water for at least 30 minutes. If using cashews, soak them alongside the posto — they blend into the paste and add a lovely creaminess. Grind into a smooth paste with a little water.
- If using fried onion, thinly slice one small onion and fry golden in mustard oil. Remove and keep aside — this goes on top at the very end.
- Heat mustard oil in a pan. Add a pinch of sugar directly into the oil — it caramelises slightly and adds a subtle depth. Add kalo jeere and let them splutter. Add slit green chillies.
- Add the potato cubes and jhinge. Stir to coat in the tempered oil. Cook on medium for 4–5 minutes until slightly softened.
- Add the posto paste. Stir gently to coat everything evenly. Add water — a little for a drier finish, more for a gravy consistency. This is entirely your personal choice.
- Add salt to taste. Cover and cook on low-medium heat for 8–10 minutes until the potato is fully cooked and the posto has thickened around the vegetables.
- Taste and adjust salt. Turn off the heat.
- Finish with a drizzle of raw mustard oil. Scatter the fried onion on top if using. Serve with plain white rice.
The posto coating the jhinge and potato — that golden, nutty crust is everything.
Baba's Three Optional Upgrades
The base recipe is perfect on its own. These three additions take it somewhere else entirely — use one, two, all three, or none.
🥜
Upgrade 01 — Cashew in the Posto SoakSoak a few cashews alongside the poppy seeds and blend them together. The cashew adds richness and creaminess to the paste without any strong flavour. You won't taste cashew — you'll just taste a rounder, more luxurious posto.
🧅
Upgrade 02 — Fried Onion on TopFry thinly sliced onion in mustard oil until deep golden before you start the recipe. Keep it aside. Scatter it on top of the finished posto just before serving. It adds a sweet, caramelised crunch that contrasts beautifully with the creamy paste.
🫙
Upgrade 03 — Raw Mustard Oil FinishBaba's signature move. A tiny spoon of raw mustard oil drizzled on top just before eating. The cooking process mellows mustard oil's sharpness — this brings it back, pungent and alive. As Baba says — that rawness adds so much.
📝
Gravy or Dry — Your ChoiceSome people like jhinge posto thick and clingy, almost dry. Others prefer a loose, flowing gravy. Neither is wrong — it's entirely personal. Add water gradually and stop when it looks right to you. Baba says cooking is a science experiment — taste and decide.
