It is so easy to make infused vodka with sous vide cooking. Try this rhubarb and orange variation for a take on homemade Aperol! It takes just 2 hours instead of several weeks for a typical infusion.
While the vodka mixture is cooking, make simple syrup. Juice the oranges into a large liquid measuring cup. After juicing, add water until total liquid is 2 cups. Combine liquid and sugar in a saucepan over low heat. Cook until sugar is dissolved, about 15 minutes, stirring occasionally. Let cool to room temperature.
Taste the mixture. Add bitters a few dashes at a time, stir, and taste. Repeat until the mixture has reached your desired bitterness. Don't be afraid to lean to the bitter side!
Store in a cool dark place or in your refrigerator.
To make a homemade Aperol spritz, add 2 oz of the homemade aperol to a large wine glass. Add a large handful of ice. Top with prosecco and garnish with an orange slice.
