Bingo!
Yes, there is some caviar on top of those little salmon "canapés" (also starting with "C"... that was going to be the second hint). And you're right, it isn't meat. It's fish roe (little fish eggs). Also, I'm not really wealthy... there are some very high-quality varieties of caviar that are REALLY expensive, but the one we bought for that dinner wasn't one of those
And finally, yes, it tastes quite salty. Truth is, I hardly ever eat it.
Anyway, enough of the random boring trivia. It's your turn, Gorfinhofin
