Vanilla Margaritas

1 part good-quality tequila
1 part Grand Marnier
1 part triple sec
1 (8-10 inch) vanilla bean

Using an empty tequila bottle, put equal parts of the mixture into the bottle. Add the vanilla bean, which you can purchase at health food stores. Let sit for at least 2 months, the longer it sits the better.

Once you open it, mix with margarita mixer and drink it on the rocks (or blended if you prefer).
