I had to try this.
Celery-Infused Tequila
1 1/2 cups tequila
2 celery leaves
1 celery stalk, cut in half
I always get the celery for my infusions from the farmer's market - I swear it has more flavor. If you can't locate any locally, try using organic celery. Infuse the tequila in an air-tight jar for two days. Shake the jar occasionally. When the allotted time has passed, strain out the tequila, bottle it, and store it in the fridge.
Verdict: Surprisingly delicious. The agave and celery harmonize beautifully. It even tastes, bizarrely, a tiny bit sweet. Take the celery tequila, pair it with lime, St. Germain and a little Lillet Blanc and you have...
