Juice and seeds from 4 passion fruit
1 ounce lime juice
2 teaspoons simple syrup, or to taste (recipe below)
1/4 ounce Añejo tequila
1/4 ounce Cointreau
1/4 cup Moët & Chandon Champagne
Place the passion-fruit juice and seeds, lime juice, simple syrup, tequila, and Cointreau in a food processor or blender, and liquefy. Strain (leave the seeds in the juice for a fruitier flavor), pour into a glass filled with ice, add the Champagne.
