Fill a Cantarito clay cup or a highball glass with ice. Add tequila, grapefruit soda, lime juice, orange juice, and salt.
Stir to combine. Garnish with a lime and serve.
Tequila: Tequila blanco is not aged, lighter in body, and perfect for making mixed drinks like this one. Tequila reposado (which means “rested” and is aged in oak for at least 2 months) is ideal for sipping.
Grapefruit soda: Mexicans usually use Fresca or Squirt (their Fresca is different! It’s not sugar-free!). If you want something made without corn syrup, look for Jarritos or Izze brand grapefruit sodas.
Salt: This is usually added as a pinch on top of the drink, but you can also salt the rim like a Margarita.
Garnish: A lime wedge is the traditional garnish. A slice of orange or ruby red grapefruit works, too.
Yield: This recipe makes 1 Cantarito cocktail.
Cantarito cups:These small clay pots are found at street fairs in Jalisco, Mexico and make a great cup for this refreshing drink. Soak the cups in water for 12 hours before use, then wash with soap and water and you're ready to go. No authentic clay Cantarito cups on hand? Just use a highball glass.
Big batch: To make a batch of 8 cocktails, combine 16 ounces (2 cups) tequila, 16 ounces (2 cups) grapefruit soda, 4 ounces (1/2 cup) fresh lime juice, 4 ounces (1/2 cup) orange juice, and 1-2 teaspoons salt and in a pitcher. Have ice, Cantarito cups, and lime slices on hand so guests can help themselves.
Paloma: Similar to a Cantarito in flavor but less fussy overall. To make a Paloma, fill a highball glass with ice. Add 2 ounces tequila and 1/2 ounce fresh lime juice, then top with grapefruit soda. Garnish with a pinch of salt and a lime wedge if desired.
