Prepare your clay cantarito cup by soaking it in cold water for 10 minutes.
Rim the cantarito cup with Tajín seasoning.
Add the tequila, orange juice, lime juice and grapefruit juice into a shaker with ice and shake for 10-15 seconds.
Strain the cocktail into a cantarito cup (or other glass) with fresh ice.
Top it off with grapefruit soda and give it a gentle stir to combine.
Garnish with fresh fruit like a lemon wedge, grapefruit wedge or lime wedge.
Notes
Tips For Making
Cantarito cups are most often used because they are known for keeping drinks cooler for longer.
Many recipes recommend adding a sprinkle of salt to the cocktail shaker before shaking. If you like a little extra salt in your beverage, give this a try.
If you don't have Tajín to rim your cup with, you can use margarita salt instead (although we love the spice and flavor of Tajín).
