Aloo Posto is a traditional Bengali recipe of potatoes cooked in a lightly spiced poppy seeds paste together with a few spices, seasonings and mustard oil. This Aloo Posto recipe is easy to prepare, flavorful, makes for a great side dish with a dal-bhaat (dal and rice) combination, and is also naturally vegan and gluten-free.
Soak the poppy seeds in ¼ cup water for 3 to 4 hours or overnight . If you forget soaking , then soak in lukewarm water for an hour or so.
After overnight soaking, use a fine mesh strainer and drain all the water.
Add the poppy seeds in a small chutney grinder.
Add 1 green chili and 1 tablespoon water.
Grind to a fine paste. Add more water if needed while grinding the soaked poppy seeds.
Making aloo posto
Next rinse, peel, and cut the potatoes into pieces measuring 1 to 1.25 inches.
Heat mustard oil in a pan or kadai (wok) and let it gently smoke on a medium heat.
Lower the heat and add ½ teaspoon nigella seeds (kalonji).
Stir and saute the nigella seeds for a few seconds.
Add the chopped potatoes. Stir to combine and mix the potatoes evenly with the mustard oil and nigella seeds.
On low heat, sauté the potatoes, stirring occasionally, until they are halfway cooked or exhibit a faint golden hue at the edges.
Next sprinkle turmeric powder all over the potatoes. Turmeric is an optional ingredient.
Stir and mix well.
Add the poppy seeds paste and two whole green chilies. Scrape of all the poppy seeds paste from the grinder jar and add. You can even rinse the jar with some water and then add the water in the pan.
Mix thoroughly to combine all the ingredients.
Cooking further
Next add ½ to ⅔ cup water. The amount of water required depends on the consistency you want. Usually aloo posto has a dry to semi-dry consistency, but for a gravy consistency you can add some more water.
Stir and mix very well.
Season with salt and mix again. You can also add sugar if you prefer.
Cover the pan with a lid and on a low heat simmer till all the water dries up and the potatoes are cooked. The poppy seeds paste will also cook by then. Do not overcook the potatoes. Do check a couple of times when the potatoes are cooking.
The consistency should be dry and there should be no water in the pan. The poppy seeds paste will also coat the potatoes.
While serving you can place some fresh green chilies if you want as a garnish or serve aloo posto as is with some steamed rice.
Serving & Storage
Serve the Aloo Posto hot, with steamed rice and/or dal. You can also pair a side of Bhaja (fried vegetables) when serving Aloo Posto with rice. If you like, pair this meal with your preferred raita or papad.
Store leftovers in the refrigerator in an airtight container for about a day. The consistency will thicken more after refrigeration. So while reheating, add some water to loosen the thick consistency.
Notes
Add water as needed to alter the consistency.
Green chili is optional in the aloo posto paste.
Turmeric powder is optional.
Ensure fresh, good-quality poppy seeds without a stale or rancid smell.
Consider adding a bit of sugar for a subtle sweet taste.
