Really easy to make mozz Kari, just follow the recipe and instead of using the oven, you setup something like in my pic in the op and just set the temp.... This is where I get all my cheese making supply.... http://www.leeners.com/cheese/store/
and the half pan and cambro from webstaurant.com....
and the place that got me on track...
