Preheat the oven to 250 degrees F. Line a baking sheet with sides with parchment paper.
To the baking sheet, add the sugar, vanilla bean and bourbon. Toss well to combine and moisten the sugar. Place on the middle rack of the oven and bake for 1 hour 1 hour 30 minutes, tossing the sugar twice throughout cooking. The sugar is done when it feels dry to the touch and has a golden, caramel hue to it. It is OK if some of the sugar clumps together, but you don't want any giant clumps, break those up while the sugar is still warm. Mix in a pinch of salt. Let cool completely before storing. Can be stored in an airtight container for up to 2 months.
