Blimey once you get your teeth into something...I can't believe you did an internet search for this in the middle of the night I only said I'd never heard of anchovies in a caeser salad, I never made a big issue of it.
Your 'how salads got their name' link states 'some recipes contain anchovies'. See that? some recipes , so why should it be so fantastic that I'd never come across it? I bet when you googled you put the word 'anchovies' in the search to make sure you got lots of the right answers, eh?
FWIW I like the sound of it both with or without the little critters
