1/2 oz Averna
1/2 oz Punt e Mes
1/2 oz Pink Grapefruit Cordial (*)
1 dash Bittermens Grapefruit Bitters
Stir with ice and strain into a coupe glass. Garnish with a grapefruit twist.
(*) An oleo saccharum of grapefruit peel and sugar; add the same amount of grapefruit juice as sugar to make a 1:1 syrup. In a pinch, a 1:1 syrup of grapefruit juice to sugar would do, and for drier palates, grapefruit juice would work; however, both of these shortcuts will lack the peel notes.
