The Beachcomber cocktail is a sweet and sour cocktail. It is named after the Beachcomber bar in the Raffles Hotel in Singapore, which opened in 1927 and was frequented by many famous guests such as Somerset Maugham and Noel Coward. The Beachcomber cocktail was developed by Ngiam Tong Boon, who worked at this hotel from 1934 to 1955.
In a Boston shaker or cocktail shaker, combine all of the ingredients. Well for for 10 seconds after adding ice. Fill a chilled cocktail glass with the liquids. The Beachcomber is a rum-based blended cocktail containing one and a half ounces. The amount of alcohol is reduced somewhat for this shaken-and-strained version. If you're serving your Beachcombers over ice, raise the rum to 2 ounces per person.
