This salad was invented in 1893 by the Maitre D' at the Waldorf Astoria in New York City. And then made beloved to us Brits by John Cleese in Fawlty Towers - the chaos created by an American guest asking for a simple Waldorf Salad is a true gem. As is the salad itself - it couldn't be easier to make, and it's really fresh and tasty.
A squirt of lemon juice.
