These Spicy Watermelon Basil Margaritas are sweet, refreshing, and spicy, with homemade chili syrup and a salted chili rim.
Rub glass rims with lime, then dip in a chili-salt mix (or Tajín). Chill glasses for best results.
Blend all margarita ingredients until smooth. Add cold water if needed. Use ice cubes for high-power blenders; otherwise, use crushed ice.
Pour into prepared glasses, avoiding overflow. Garnish with basil, watermelon, and lime. Serve immediately and enjoy!
