I have a milk cow so buying the milk is not an issue but have made Butter, Cheddar, Cream cheese, Cottage cheese, mozzarella, Ricotta and sour Cream. All of them seem to be super easy, but as I have never seen it done and have only found recipes off the internet the results are quite different. I think the difference is most recipes are for store bought milks instead of raw. so my advice would be Try making cheese it is a Blast! but just check your formulas for raw or store bought milk as they seem to be Completely different.
