Macher Tok belongs to West Bengal cuisine that our family never made. This is similar to Assamese counterpart Masor Tenga. We grew up eating simple traditional food that belonged to my parent's native land Noyakhali, in erstwhile East Bengal, now Bangladesh. There is a slight difference between two Bengal's food culture and each side has its own unique ways preparing the food. Tamarind in this recipe is very exotic and drool worthy. Every household makes it differently. This is my close friend's family recipe and I prepare exactly that way.
