Limoncello
Peel some lemon zest, add it to your vodka, and let it sit in direct sunlight for a few days. After straining out the peels, mix in sugar to taste. What you're left with is a much less cloying, citrusy liquor.
(Note: higher-proof grains work better because they will extract more lemon flavor, making your foul-tasting vodka taste smoother.)
Vodka Sauce
Stir a shot of vodka into a simmering pot of crushed plum tomatoes, heavy cream, and Italian herbs. Cook off the alcohol until the sauce thickens slightly, then add a fat pinch of Parmesan as the final touch.
Drunken Shrimp
Add a splash of vodka to a shrimp stir fry to remove some of the fishy flavor. Although a majority of the alcohol will evaporate while cooking, the vodka will add a complexity of flavor without much effort.
Popsicles
Combine vodka with any fruit puree and freeze for a refreshing adult snack.
Homemade Kahlúa
Coffee liquor can be made at home with just a few ingredients, including cheap vodka. After freshly brewing two cups of strong coffee, add four cups of sugar, and another two cups of vodka. For additional flavor, add a pod of vanilla bean.
DIY vanilla extract
Slice vanilla beans and place them in a bottle with a cup of vodka. Keep the beans in there for eight weeks, shaking the mixture occasionally, and you're left with flavorful homemade vanilla extract.
Cheesecake
Give your cheesecake a Polish twist by infusing vodka into a sweet berry compote glaze. To avoid the harsh taste, a good rule of thumb is to use the same amount of alcohol as you would use vanilla extract.
Sunshine Bitters
This aromatic cocktail additive gets its name from its amber color. Combine crushed cardamom, saffron, and orange peels to create this delicious bitter — a must for any aspiring mixologist to have in their pantry.
