Ahh, Sapporito! Haven't tried that yet, but I'm sure to pick up a can next time I visit my trusty restaurant supply store. I'm allow positive ive seen it there.
Re: colors, I haven't edited these photos or color corrected in any way. They look a little "cool" probably because they were just taken around noon in natural daylight.
Another interesting thing I noted that day was how heavy handed they are with the Romano and relatively light they are with the mozz. I decided to give it a try this past bake and really enjoyed the results! Also, for anyone in north NJ the bags of pecorino Romano that they sell at corrados (both the supermarket and the wholesale) are probably my favorite and come much closer to the taste I'm going for than those little tubs you find at most grocery stores.
