The London Sour is a long Scotch sour: blended Scotch shaken with fresh orange and lemon juice, orgeat and sugar syrup, served over ice.
The London Sour was created by Victor "Trader Vic" Bergeron, the founder of the Trader Vic's tiki restaurant chain, to mark the 1963 opening of the London branch of Trader Vic's, housed in the London Hilton on Park Lane. The choice of Scotch whisky as the base spirit nodded to the drink's British namesake city.
The recipe, built on Scotch, orange and lemon juice, and orgeat, was later published in Bergeron's own 1972 Trader Vic's Bartender's Guide, which remains the documented source for the original formula.
60 ml blended Scotch whisky, 75 ml fresh orange juice, 15 ml lemon juice, and 5 ml each of orgeat (almond syrup) and sugar syrup. It is a long, citrus-forward take on the whisky sour.
