Not cheese slices for sandwiches, but real cheese that is pre-sliced in little plastic trays, about the right size for crackers, for example. I used to buy the “extra sharp” cheddar by Cracker Barrel that way, just because it was handier for snacking, but my store stopped carrying them (or CB stopped selling them, I don’t know which). So I tried another brand, Cabot.
I don’t remember now exactly how the Cracker Barrel cheese was sealed, but I never had a problem with its condition. But the Cabot cheese isn’t vacuum sealed, and I had to throw out about half of the package that I bought because some of the pieces were dried into rubber, and some of them were moldy, and some of them were mushy from extra moisture. I didn’t try to get a refund or anything from the store, but when I went back and looked at the other packages (the packaging is clear) I could see moisture condensation on the inside of the package, and I could also see that some of the slices looked dried out. I pointed this out to the store but they just said “Oh, I’m sure it’s fine” even when I told them about my experience.
So here’s a warning and recommendation: don’t buy Cabot pre-sliced cheese in the plastic tray, but the Cracker Barrel should be OK, if you can put up with their politics and their business practices.
