Part 1: Pecan Pie Bourbon
- In a large dry skillet, toast the pecans over medium heat until light golden and fragrant, about 2–3 minutes, stirring halfway through.
- Transfer toasted pecans to a quart-sized mason jar. Add the vanilla beans and bourbon.
- Seal the jar and store in a cool, dry place to infuse. It can be used after 1 week, but flavor improves with at least 1 month of infusion.
Part 2: Pecan Pie Old Fashioned
- Run a strip of orange peel around the rim of a highball glass (optional).
- Add simple syrup and bitters to the glass and stir.
- Fill the glass with ice, then pour in 2–3 oz of pecan pie bourbon.
- Stir gently and garnish with the orange peel. Serve immediately.
