Land O’ Lakes American is also a process cheese, like Kraft Deli Deluxe.

Perhaps, but it’s still far superior to those rain slicker squares you get from the dairy case.

No argument here. That’s what I buy when I want to get easy melting cheese.

But the yellow of school buses usually is sort of orange-y. Pure yellow, IMO, would be about the color of a daffodil, or of the tulip shown here. School buses, and taxis, seem to be more the color of the Lego bricks pictured directly below the tulip.

Why is 'green" cheese green? And what does one do with 'sapsago" cheese? (It is supplied in little rock-hard pellets). I’ve yet to see anyone use it.
