Bud Butter with diffrent types of dairy

[Arobskittle]

So i was reading some posts about people making Bhang on their own, and i read up a little about traditional bhang, and it seems they add a type of clarified butter called ghee or something.
The clarified butter caught my eye http://en.wikipedia.org/wiki/Clarified_butter
and then i found this

mega chart of all the milk products

so using clarified butter to make weed butter could you make super concentrated weed butter?
Does a super high fat content really mean that much ?
what else on that chart looks good to use? like some sort of buttermilk bud milk you can throw in a milkshake, or bud whippped cream?
Also i feel like nobody ever says what type of butter is best, salted or not sweet cream etc

Yes, fat content does matter since THC(&other cannabinoids?) is fat soluble, therefore more fat -> more potency.
