Here’s a few things to keep in mind:

  • the liquid ingredients are poured into a shaker (with ice) to combine, shaken, then poured over ice
  • many Longhorn bartenders don’t use jiggers when making the drinks
  • the taste of the drink will vary from location to location
  • they put watermelon flavored sugar on the outer rim
  • make it in small batches and tweak this recipe to your taste

To save calories, try a “skinny” sour mix recipe:

  1. 1 cup stevia syrup (that’s 1 cup of water + 2 1/2 tsps white stevia powder)
  2. 1 cup fresh lemon juice (or 1/2 cup lemon and 1/2 cup lime juice)


  1. Add liquors and all other ingredients to a martini-like shaker. Fill with ice. Put on shaker’s lid. Shake.
  2. Wet lip of margarita glass with water and then dip into superfine sugar that is colored and flavored with a drop of Monin syrup. You’ll have play with the amount… mix the sugar with a drop of syrup and then stir.
  3. Strain and pour into a glass or over ice. Enjoy!
