That was very informative, thanks!
It seems clear now that Pure Indian Food's (PIF) ghee is butter oil + butter wax (first time I've heard of butter wax!) and Green Pasture's (GP) butter oil has the butter wax removed.
The question is, how much butter wax is in ghee? I have not received my ghee yet (only placed the order today) so I can't try to guesstimate by looking. Let's just say ghee is 50% butter oil and 50% butter wax. If that was so, I'd have to take twice as much ghee as butter oil get the same benefits. PIF's ghee is less than $.08/ounce (28.8 oz bottle) and GP's butter oil is $3.75/ounce. Taking twice as much ghee still only costs me $.16 an ounce.
I have not read about GP's quality, but I have read on PIF's website about their butter, cows, farm, and am very happy with what I have read. Their cows are fed rapidly-growing grass, the milk is non-homogenized, ghee made from said cows summer to late fall only, on the waxing moon (if that matters to anyone lol), butter melted on low heat in stainless steel pots, ghee placed in glass bottles. I am not sure how Green Pastures' quality can be any better.
