The diki-diki is a cocktail made with calvados, Swedish Punsch, and grapefruit juice, dating back to the 1920s where it was popular in London's higher-end American bar scene but is now more commonly served as a Tiki drink. The original recipe calls for shaking the ingredients with ice in 2:1:1 proportions,[1] although many later variations have modified the ratio to greater emphasize the calvados as the base ingredient (4:1:1).
