Truffle is a bit like saffran – it’s incredibly expensive but there’s something in it, a flavor you can’t really get elsewhere. If you want to feel Superior to Silly Rich People who just do things to show off how much money they have, truffle is not your starting point.
Caviar, however, is salty fish cum with no redeeming qualities. It doesn’t taste bad, it tastes like disappointment. If you want to make fun of stupid rich people nonsense, caviar is a fine place to start.
