Here's the thing about string cheese: It is to be strung, then rhythmically whipped into the mouth. It should never be chomped straight from the stick. People who think otherwise are not to be trusted.
String cheese is the ultimate "play food;" it's been providing entertainment straight from the brown bag for ages. The reason it strings? The temperature at which mozzarella is heated -- a fiery 140 degrees -- realigns the milk proteins, which transforms the cheese solid into tearable strands.
