In a bowl add the paste to the mince along with the gram flour, turmeric powder, crushed chillies, salt, and coriander seeds. and then mix until all the ingredients have been incorporated.
If the mixture is soft, then refrigerate for 30 minutes. (Optional)

Using your hands add some oil or water, form balls in your hands, and then flatten them to form a circular shape, about 1cm thick before deep frying them in a pan.

When cooked and both sides are evenly browned remove and set aside on a paper towel.
