This Spicy Sparkling Citrus Margarita is a bit tart,a bit sweet, with a kick from jalapeno and a sparkle from champagne. Perfect for the big game.
In a cocktail shaker, combine tequila, Grand Marnier, lime juice, orange juice and, if using, a teaspoon of agave nectar. Add a slice to two of jalapenos, with or without the seeds, depending on how much heat you prefer. Muddle these together. Prepare glasses by rubbing rims with a wedge of lime and dipping into coarse salt. Fill with crushed ice. Strain cocktail mixture and divide between 2 glasses. Top each glass with sparkling wine or champagne. Garnish glasses with a lime and half an orange slice and a few slices of jalapeno.
