A richly seasoned aloo posto is the ultimate combination of tender potatoes and a unique posto or poppy seed paste gravy. A delicious vegan or vegetarian side or main dish.
Place the poppy seeds and water into a bowl and soak for 5 hours up to overnight.
Drain the water off of the seeds, then grind them and the green chili into a smooth paste in a food processor, chutney grinder, or with a mortar and pestle.
If needed, add additional water one tablespoon at a time to make the paste.
How to Make Aloo Posto
In a large skillet, heat the mustard oil and nigella seeds for 1 to 2 minutes until aromatic.
Add in the chopped potatoes and saute for 4 to 5 minutes until the potatoes are beginning to brown around the edges and are about 60% cooked through.
Next, add in the turmeric powder and salt, and stir to combine.
Add the poppy seed paste and mix well coating the potatoes. If you want more heat, add in sliced green chilies at this point.
Simmer over low heat until all liquid has evaporated. If it seems too dry, you can add water by the tablespoon to create the consistency of gravy you prefer.
Garnish with fresh sliced chilies and serve with rice.
