Lime Simple Syrup

The simple syrup is easy to make and adds sweetness and flavor to everything from iced tea to a homemade cocktail. In this version, there is a piquant note of lime.
Cook the sugar and 1/2 cup water in a small saucepan over medium-high heat, stirring constantly, for 3 minutes or until the sugar is dissolved. Remove from heat; add lime zest and lime juice. Cover and refrigerate for 1 hour.
