DIY Blue Curaçao Recipe (Plus Non-Alcoholic Version)

0 Wash and dry the oranges, then remove their peels with the vegetable peeler.
1 Combine the orange peels with the sugar, mixing thoroughly to ensure the peels are fully coated.
2 Cover the mixture and let it sit on the counter for 12-24 hours, or until nearly all of the sugar has dissolved.
3 Pour in the warm water and stir to dissolve any remaining sugar.
4 Remove the orange peels from the liquid, then strain the liquid through a fine mesh strainer to remove any remaining bits of orange peel.
5 Stir in the alcohol and food coloring, then bottle in glass bottles or jars.
6 Store the liqueur in the refrigerator. It will keep for at least one month.
