The name of this drink, invented in Harry's New York Bar in Paris, was a term specifically applied to frequenters of speakeasies, flouters of the National Prohibition Act in the US. "It's a very versatile drink," says Mike Enright, author of Palmer & Co's cocktail list. "Pre- or post-dinner. You could even drink it in the bath, though perhaps not the shower." Enright recommends using Monin or Crawley's grenadine.
Note A Nick and Nora glass is a curved-bottomed coupe; many such glasses have a smaller capacity than a cocktail glass.
