Ruby-Red Margarita

"If your crowd is into margaritas, try a version with Texas grapefruit instead of lime—colorful and delicious!"
—Sarah Kane, Culinary Art Catering, Dallas

Fill a cocktail shaker with ice; add 1 oz. silver tequila, oz. triple sec, 2 oz. ruby-red grapefruit juice, the juice from half a lemon and half a lime, agave nectar (to taste), and 2 to 3 grapefruit segments. Cover and shake until very cold. Pour into a salt-rimmed glass and garnish with a grapefruit slice.
