Wildly popular in Mexico, this drink is delicious and tart. Traditionally it's made with grapefruit flavored soda, but we ditched the store bought soda and made it 100 percent natural.
2 parts tequila
3 parts fresh squeezed ruby red grapefruit juice
Topo Chico Mineral Water
Pour tequila and grapefruit juice over ice and stir.
Squeeze lime wedge into drink and top with a splash of Topo Chico Mineral Water.
