When I get home I'll post some of the links I've found if you want. I'm at work so on a different pc. Apparently though you can buy milk that has not be homenigzed (i know I've butchered that spelling).
I've made ricotta cheese, but I think I let the curds sit at the top of the soured milk for too while it was heating. The result was like chewing small bits of rubber! lol Think I need more practice!
I've had a bit of success with making labna, which is yoghurt wrapped in cheesecloth and strained over a bow in the frig for a day or two to get the liquid out. Don't know that it qualifies as cheese exactly but the vegetarian son in law can't get enough when he descends on us. Slathers it on toast with chilli jam.
