Make the orange peel simple syrup by combining the orange peels, sugar, and water in a saucepan over medium heat. Whisk it until the sugar dissolves then remove it from the heat. Let it cool and store it in the fridge (you’ll have leftovers for more margaritas).

To make the margarita, fill a cocktail shaker or a mason jar with ice. Then add the simple syrup, orange juice, and lime juice. Give it a good shake and strain into a glass with ice.
