A floral and sour liqueur cocktail ∙ Dry shake ∙ 5 min ∙ 7.3% ABV ∙
The Elder Sour is an egg-white sour of elderflower liqueur and fresh lime juice, double-shaken, with an optional dash of orange bitters.
The Elder Sour is credited to a British drinks writer, who created it in London in 2006. It emerged early in a wave of cocktails built around elderflower liqueur, a category that gained wide popularity in bars after the French elderflower liqueur St-Germain launched in 2007. The drink follows the classic sour template, pairing the floral liqueur with citrus and egg white in place of a base spirit, and is cataloged among the sours family of cocktails alongside other elderflower-based drinks the same writer developed around the same time, such as the Elderflower Daiquiri.
60 ml elderflower liqueur, 30 ml fresh lime juice, 15 ml pasteurized egg white and an optional dash of orange bitters.
Shaken twice. Shake it with ice first to chill and dilute, then strain it back into the empty shaker. Shake again without ice for 15-20 seconds; that second shake whips the egg white into a thick foam.
An old-fashioned glass filled with ice, garnished with a lemon wheel and a maraschino cherry.
