Haaor Koni Anja

For 4 servings
- boil · ~10 min
Hard-boil and peel the duck eggs.
Place duck eggs in a saucepan, cover with water, and bring to a rolling boil. Boil for 10 minutes. Drain the hot water and immediately transfer eggs to a bowl of cold water. Let them cool completely, then gently crack and peel the shells. Prick each egg with a fork a few times to help them absorb the gravy.
TIPDuck eggs have thicker shells than chicken eggs. A slight crack before plunging into cold water helps the shell separate from the egg. - fry · ~4 min
Fry the boiled eggs until golden.
Heat 1 tablespoon of mustard oil in a frying pan until it reaches its smoking point and the raw smell dissipates. Reduce the heat to medium and carefully slide in the boiled eggs. Fry them, turning gently with a slotted spoon, until the exteriors are blistered and golden brown all over. Remove the eggs and set aside.
TIPPricking the eggs beforehand prevents them from bursting in the hot oil. Don't skip the step of heating mustard oil until it smokes—this removes its pungent raw bitterness. - temper · ~11 min
Sauté the onions and aromatics.
1.Pour the remaining 2 tablespoons of mustard oil into the same pan and let it heat up again.2.Add the finely chopped onions and fry on medium heat until deep golden brown (8-10 minutes).3.Stir in the ginger paste and minced garlic, and sauté for 1 minute until the raw aroma disappears. - saute · ~7 min
Build the tomato-spice masala.
1.Add the tomato puree, turmeric powder, red chili powder, cumin powder, and coriander powder to the pan.2.Stir continuously and cook the masala on medium heat until the tomatoes break down, the oil starts to separate from the mixture, and the raw spice smell is gone (5-7 minutes).3.Splash a tablespoon of water if the spices start to stick to the bottom of the pan.TIPCook the masala patiently. Rushing this step will leave a raw tinny taste from the tomatoes and powders. - simmer · ~10 min
Add the eggs and simmer in the gravy.
1.Pour in 1 cup of warm water and add salt. Stir well and bring the gravy to a gentle boil.2.Slit the fried eggs halfway down the middle (without cutting through completely) or leave whole, and gently nestle them into the bubbling gravy.3.Add the slit green chilies. Lower the heat, cover the pan, and simmer for 8-10 minutes to let the eggs soak up the flavors.TIPSlitting the eggs and tucking them cut-side down allows the spicy masala to penetrate the yolk, making every bite rich and flavorful. - garnish · ~5 min
Finish with garam masala and fresh coriander.
Turn off the heat. Sprinkle the pinched garam masala and freshly chopped coriander leaves over the curry. Let the dish rest covered for 5 minutes before serving to allow the flavors to meld.
