Cantaloupe Margarita with a Hint of Mint

Combine cantaloupe and lime juice in a food processor; process until pureed. Strain mixture through a fine sieve over a bowl, stirring. Discard solids. Measure 6 ounces cantaloupe juice (reserve any extra juice for another use).

Place cantaloupe juice, tequila, Grand Marnier, and agave in a cocktail shaker filled with ice. Shake vigorously; strain into 2 ice-filled glasses. Clap each mint sprig between palms; garnish each drink with 1 sprig.
