Hi Shan,
I tried making mozzarella with the refrigerated milk and it did not work. I believe that it is ultra pasteurized and I know that boxed milk is. This denatures the milk protein & changes the structure. You can't make hard cheeses with it but can make yogurt, cream cheese and buttermilk. I've seen suggestions of using dried milk with some cream added, if good milk isn't available but have never tried this. The raw milk I get, I pasteurize myself.At Lacteos Mama Lupita, in Chapala, the raw milk is 8.50/L, It's listed as Leche Entera and I've been told that it's called Leche Broncha too.
