Cranberry Vodka Tonics
- 1 pound fresh cranberries
- 1 cup sugar
- 2 teaspoons vanilla extract or 1 vanilla bean, split lengthwise
- 3 cups vodka
- 1 liter tonic
- Lime slices, for garnish
Combine the cranberries and sugar in a medium saucepan over medium heat. Add the vanilla extract or split vanilla bean and cook, stirring, until the cranberries burst, 5 to 6 minutes.
Divide the cranberry mixture between 2 large mason jars. Divide the vodka between the jars. Cover and refrigerate for 1 week. Strain out the cranberries. Store the flavored vodka in a clean jar in the refrigerator.
For each drink, pour 2 ounces cranberry vodka over ice in a tall glass; top with tonic. Garnish with a slice of lime.
