So I've told you how easy it is to make orange infused vodka. Simply stuff a bottle with the peel of two Valencia oranges and fill up with vodka. Stick it in a dark place and let it sit for 6 weeks 'til whenever. Unlike limoncello, where you don't leave the peel in so long for the infusion process, orange vodka doesn't turn bitter the longer the peel sits. With other fruits, test the flavor at the six week mark and see if you like how it tastes.
