Fill cocktail glass (high ball or low ball work well) with ice, then fill cocktail shaker ¾ full of ice. Add tequila, orange juice, soda water, and simple syrup- to shaker. Shake for 30 seconds and strain into cocktail glass. Garnish with a piece of orange peel.

The ratio of sugar to water in this simple syrup is not the classic 1:1, and the reason for this is simply preference. For people who like drinks a little less sweet like I do, then this is the way to go. If you know you’re someone who prefers a sweeter drink, simply increase the amount of sugar to ¾ cup or 1 cup.

For the Rosemary-Orange Syrup

Combine all ingredients in a small saucepan over medium heat. Bring to a boil, stirring until sugar dissolves. Remove from heat and cool for 15 minutes. Strain through a fine mesh sieve into a glass container fitted with a lid.

Store refrigerated, in an airtight container for up to 2 weeks.
