1. To make the Jalapeño Grapefruit Margarita: In a shallow plate, combine sugar and pepper. You’ll use this mixture to rim the glasses.

2. Combine all the ingredients in a pitcher and stir well to combine. Keep refrigerated for 30 minutes to 2 hours, checking spiciness from time to time. Remove the jalapeños from the drink once the desired spiciness is reached.

3. When ready to serve, rim your glasses in the sugar and pepper mixture. Add ice cubes to each glass and pour the Jalapeño Grapefruit Margarita over. Add a grapefruit, a lime wedge, and jalapeño slices for garnish, if desired.
