Inspired by the colors of the Mexican flag, this drink is served in 3 separate shot glasses consisting of tequila (white), fresh lime juice (green), and sangrita (red)-a spicy tomato-based chaser. Each serving requires 1-ounce each of tequila, lime juice, and sangrita. The sangrita part of this recipe will make enough for 14 (1-ounce) shots. Sangrita can be stored covered in the refrigerator for up to 5 days.
