Keep a palta to stir at the base of the handi, tomatoes, can stick to the base and result in burnt gravy.3
Keep the above in mind and stir occasionally.4

Remove the masala potli and pulverize the rest of the contents of the handi.6
Return the pulverized contents to the handi and again set on a medium flame.7
Take a part of the butter and heat it in a pan to melt it.
