It’s said that the Seapea Fizz is named for song writer and composer Cole Porter (the sound of the name mimicking Porter’s initials, C.P.). The pale green cocktail is a simple—yet bracing—mix of sugar, lemon and absinthe, but this somewhat astringent mixture is not to everyone’s taste.
Add all ingredients to a cocktail shaker and dry shake. Add ice and shake until well-chilled.
Strain into a coupe and top with soda water.
The cocktail first appears in Frank Meier’s The Artistry of Mixing Drinks from 1934
