Milk based ice creams of Nic costs on an avg around 300 for 500ml pack which is around 380g & Nic is at best a mid tier brand. Animal fat is not used in making any ice cream from known established brands unless it is a quality rule violation.Normal 1L milk is now costing almost 61-62/litre, if you make cream/cheese from it, you wont even get 100gms (rough idea from my cheese making endeavors) from it, how do you think even more expensive franchises are managing to give milk based ice-cream and not frozen deserts which are made of animal fat/oil churned with sugar? I doubt their prices are lower than 40rs/litre even if they do buy in bulk.
