1 cup sugar
1/2 teaspoon peppermint oil OR 2 teaspoons peppermint extract (For stronger mint taste, add 3/4 teaspoon of peppermint oil or 3 teaspoons of peppermint extract)
3 cups Vodka
4-6 drops red or green food coloring (optional)
Now, into a sterile quart jar with tight fitting lid, pour the vodka, sugar syrup, and peppermint oil or extract and stir well (For a sweeter, thicker liqueur, add more sugar syrup). There you go! That's all there is to it. Store your delicious creation in a cool, dark place, allowing it to steep for 2 weeks. Turn the jar upside down every 2-3 days to mix, or remove lid and stir.
