Boil chicken in a pot until completely cooked. Cool the chicken and mince it or pulse it in a blender.
Add onions, mashed potato (optional), chili, garam masala, ginger garlic paste, salt, red chili powder, turmeric and coriander leaves.
Mix all together and add flour little by little only as needed. Knead the mixture to a dough without adding water. Onions release moisture and bind the mixture well.
