In my experience eating wholefood in overall terms is not expensive, especially when you factor in not paying for tobacco anymore. Where I am you can buy 2kg of generic brand butter for the same price as a packet of cigarettes to give an example. Dripping that I use for meat pan frying is cheaper than even the cheapest vegetable oil.This is usually cottonseed oil, with the last squeezing obtained with chemical solvents (these are chemically very similar to gasoline/petrol. In fact it you could probably run an internal combustion engine on it.) Buying ready made ghee is a bit pricey but it is not that expensive to make your own.
