The Diki-Diki is a cocktail drink with calvados, Swedish Punsch, and grapefruit juice. It first appeared in the 1920s when it was popular in London's higher-end American Bars. Nowadays is more commonly served as a Tiki drink. The initial recipe calls for shaking the ingredients with ice in 2:1:1 proportions. Over time later variations have modified the ratio to greater highlight the calvados as the base ingredient (4:1:1). The Diki-Diki is presently served primarily in Tiki bars. A tiki bar is a themed drinking place that serves decorated cocktails, especially rum-based mixed drinks such as Mai Tai and Zombie cocktails.
