This homemade cola recipe is a simple blend of citrus and spices with sparkling water for a less ultra-processed version of your favorite soda. The syrup base makes between 4-6 servings.
Using a peeler, remove the peel from the orange, lemon, and lime. Add all the ingredients except the sparkling water to a small to medium sized pot. Bring everything to a boil over medium high heat, then turn the heat down to maintain a simmer for 15 minutes. Remove the cinnamon stick. Turn off the heat and let cool for 15 minutes.
Strain the syrup through a fine mesh strainer into a jar to use as a base. You will end up with around 1 cup of syrup. Pour about ¼ cup of syrup over ice and top with sparkling water - can use more or less depending on your preference for flavor and sweetness. Stir to combine. Add freshly squeezed lime juice on top (can garnish with a slice of lime).
Notes
If you prefer a stronger citrus flavor, you can grate the citrus peels instead of peeling.
Some readers reported success with using coconut sugar instead of brown sugar. I personally think the brown sugar is a more accurate flavor.
Cola syrup will store well in the fridge for up to 7-10 days.
