Chingri Cutlet aka Bengali Prawn Cutlet is a famous seafood appetizer.
If not available with breadcrumbs, take 4 slices of bread/ rusk to prepare breadcrumbs. In case you are using bread then you have to grill pieces of bread for 10 minutes. However, for rusk, you can prepare crumbs directly. I prefer to use bread.
Grind the grilled bread or rusk to make the breadcrumbs.
