If you like this classic cocktail you will love my keto version with 0 carbs.
In a small sauce pan, add water and Swerve sweetner. Bring to a simmer and mix until the sweetener dissolves. Set aside to cool.
In a shaker bottle or small pitcher, add all of the ingredinets but only 1 tablespoon of the simple syrup. Taste to see if you want to adjust the sweetness.
Use two tall glasses filled with ice and pour the drink over top. Garnish with a slice of lemon.
If you want more orange taste you can also add orange zest to the drink.
