You can do some of this at home too. I buy raw milk (it's common here in Switzerland) and make paneer or ricotta. Then I boil down the whey and make a fudge-like Norwegian cheese.
Another pathway is to start with 35% fat cream or crème fraiche and make butter. Then you use the buttermilk to make cheese. Then you use the whey to make Norwegian cheese OR if you started with crème fraiche you take the sour whey and make sorbet by mixing it with some fruit juice and shaking the container every hour or so as it freezes in the freezer.
It's not nearly as time-consuming as it sounds and the rewards are better than anything you'd buy. The butter is better (less water within), the paneer and ricotta are so much better than factory-made, and the sorbet is... well probably about equal to sour cream sorbet you'd buy (assuming you buy movenpick :).
