Wash your fresh oranges thoroughly. Use a vegetable peeler to remove the zest in strips.

In a large mason jar, combine the vodka, gin, dried bitter orange peels, fresh peels, and cloves. Seal the jar tightly and give it a good shake. Store the jar in a cool, dark place for 15 to 20 days. Give it a gentle shake every few days.

After the infusion period, strain the alcohol through a fine-mesh sieve lined with a coffee filter or cheesecloth. Discard the peels and spices.

In a saucepan over medium heat, combine the sugar and water. Stir until the sugar is completely dissolved to make a rich syrup. Do not boil. Remove from heat and let it cool completely to room temperature.

Pour the cooled syrup into your orange-infused alcohol. Stir well. Now for the fun part: add the blue food coloring one drop at a time until you reach that famous electric blue hue (usually about 8 drops).

Pour into a clean glass bottle and seal. Let it rest for one week before using.
