Combine mashed and boiled potatoes with green chillies, coriander leaves, red chilli powder, dry mango powder, cumin powder, garam masala, and salt. Mix everything together evenly.

Make equal pieces of the dough and filling. Place some potato filling in the centre of a small disc of rolled-out dough, then gather the sides and seal. Delicately shape into a thick kulcha, either oval or circular.

Put a frying pan or skillet over medium heat. Cook the kulcha until it starts to become golden, then remove it from the heat. Cook the other side by turning it over. Before finishing each kulcha, brush them with ghee or butter.
