This drink was one of the 20 tequila and mezcal cocktails on Mayahuel's opening menu (there are now about 45 on the list). The name references the Pink Floyd album that Ward listened to over and over while constructing the bar. Great Martini Recipes
Fill a cocktail shaker with ice. Add all of the remaining ingredients except the garnish and shake well. Strain into a chilled coupe or martini glass and garnish with the grapefruit twist.
Very nice drink. An elaborate combination of flavors!
