Method
Prepare Your Glass:
If you like a salted rim, rub a lime wedge around the edge of your glass and dip it into coarse salt or Tajín. Set aside.
Mix the Ingredients:
In a cocktail shaker, combine the guava juice, tequila, fresh lime juice, triple sec, and agave syrup (if using). Fill the shaker with ice.
Shake It Up:
Secure the lid on the shaker and shake vigorously for about 15-20 seconds until the mixture is well chilled.
Strain and Serve:
Strain the mixture into your prepared glass filled with ice (or straight up, depending on your preference).
Garnish:
Add a lime wedge and a slice of fresh guava for a beautiful presentation.
Variations
Frozen Guava Margarita: Blend the ingredients with ice for a slushy version.
Spicy Guava Margarita: Muddle some jalapeños in the shaker before adding the other ingredients for a spicy kick.
Guava Mocktail: Omit the tequila and triple sec, and use sparkling water instead for a refreshing non-alcoholic version.
