First, soak the poppy seeds in water for 10 minutes.
After soaking, drain the water and blend the poppy seeds with 2-3 green chilies and ½ teaspoon of salt until smooth. A mixer grinder works well for this, but you can also use a traditional grinding stone or Shil nora. If the paste is too thick, add 2-3 tablespoons of water.
Next, roughly chop two medium onions. If your onion is large, one will be enough for 100g of poppy seeds.
Slice 2-3 green chilies.
Chop one large tomato. While optional, adding a tomato to this dish helps balance the flavors.
Now, heat 2 tablespoons of mustard oil in a pan.
Once the oil changes color, add the chopped onions and cook until they are light pink. Be careful not to overcook them.
Then, add the chopped tomatoes and 1 teaspoon of salt.
Continue cooking until the tomatoes soften and the oil separates from the mixture.
Finally, stir in the sliced green chilies.
Blend and combine the ingredients.
Once cooked, allow it to dry until oil separates around the edges.
Now add posto bata or poppy seed paste and mix it.
Add one cup of water and let it evaporate while cooking in the pan.
For a richer color and stronger flavor, stir in one tablespoon of mustard oil.
Mix well, then turn off the heat.
Serve the Piyaj Posto with hot rice!
