I tried this stuff at home, in a Sicilian pie. I made an 8" square pie, with a layer of provolone slices on the bottom. Then I added Arrezzio on one side and Sorrento on the other. I had to use the provolone, to simulate the pizza I made at church. I baked at 550 right over the heating element, and I gave it 9 minutes. Then I put it on a stone for 30 seconds, with the pan removed.
They both baked up beautifully. The Sorrento barely browned. The Arrezzio browned a little, but not much. It seemed like the Sorrento had a better flavor. Neither seemed as bland as Grande, so I would prefer either of these to it.
I think if I were picking a new cheese, I'd go with Sorrento, because I need a cheese that won't burn, and I like the flavor. But NOTHING I've tried matches the flavor of Kirkland cheese, as far as I can tell! It amazes me that Costco cheese is that good.
I guess I better continue this unpleasant research.
