In your cooking pot, heat a tablespoon of oil over medium heat and add the onions. Fry until they turn light brown and then add the chilis, ginger and garlic
Once they become fragrant add the fish chunks with all the spice powders, sugar and salt. Mix throughly and cook for 3-4 minutes
Then add the mashed, boiled potatoes and mix well, until evenly combined. Check for salt here and adjust if needed
Turn the flame off and mix in the peanuts and coriander leaves. Let it cool down enough for you to be able to shape them
Set up your crumbing station. Pinch out golf ball sized portions out of the cooked fish and potato mixture, shape and flatten them out in small patties
Dredge each patty in flour, then the beaten eggs and then roll them in the bread crumbs**
Once all of them are shaped, heat the remaining oil and then turn the flame to medium. Fry the patties in batches, until both sides turn golden brown
Remove on absorbent kitchen towels and drizzle a pinch of pink/black salt over each cutlet. Serve your lip smacking macher chop (Bengali fish cutlets) with some kasundi and/or ketchup. Enjoy!
