Hershey's chocolate
I was watching some documentary series "The Food that Built America" (worth a watch) and it discusses Mr Hershey and his special way of making chocolate which apparently uses soured milk.
Anyway, today I'm in the supermarket and tucked away I noticed a Hershey bar. I've never had one so I thought I'd taste this sour stuff. It tastes like eating stale vomit. How is this America's chocolate bar? It's disgusting.
