Now, heat 1 tablespoon of oil in a deep pan and fry the lentil dumplings (Daal-er Bori) until golden.
Remove the dumplings and set them aside. Add another tablespoon of oil to the pan and heat.
Add the potato wedges along with ¼ teaspoon of salt and fry until golden brown.
Remove and set aside.
Add another tablespoon of oil to the pan and heat. Add the eggplant wedges and fry until golden and crispy.
Remove and set aside.
Now, add 2 tablespoons of oil to the pan. Carefully fry the marinated fish over medium heat, being careful not to break it. Once golden, remove and set aside. (Check the recipe video for tips on frying the fish.)
Leave the remaining oil in the pan.
Add Panch Phoron to the oil to temper it, then add the chopped onions and fry until they turn light pink.
Add the chopped tomatoes and let them cook over low heat.
Add the garlic paste as well. Now, add a little water and cook until the oil separates from the mixture.
Next, stir in the red chili powder.
Add one cup of water and bring the mixture to a boil.
Then, add two more cups of water. Gently fold in the fried potatoes and coat them with the spices.
Let the mixture simmer over medium heat until it boils and the potatoes become tender.
Carefully add the fried fish, stirring gently, and bring everything back to a boil.
Now, add the fried eggplant and fried bori. Boil for about a minute, then stir in ½ tablespoon of raw mustard oil.
If needed, add a little more water, as this curry is traditionally served with a slightly thin sauce.
