Orange liqueur is a versatile spirit that can be enjoyed on its own, used in cocktails, or added to desserts. To make homemade orange liqueur, you will need oranges, vodka, sugar, and water. Start by zesting the oranges and infusing the zest in vodka for a few weeks. Then, make a simple syrup by boiling water and sugar together. Combine the infused vodka with the simple syrup and let it rest for a few more weeks. The result is a bright and citrusy liqueur with a hint of sweetness. Use orange liqueur to make cocktails like Margarita or Cosmopolitan, or add it to desserts like orange-flavored cakes or creams.
