Preheat oven to 350 degrees.

Combine butter, brown sugar, salt, cayenne and whiskey in a small saucepan over medium heat. Whisking constantly, cook until the butter has melted and the mixture has formed a smooth sauce. The process should take 8-10 minutes.

Spread the bacon slices on a cooling rack set over a baking sheet. Bake in preheated oven for 10 minutes, turn slices and bake for another 5 minutes.

Remove from oven and brush with glaze.

Return bacon to oven and bake 5 minutes. Repeat basting every 5 minutes until bacon is brown and crisp. About 35 minutes.

Cut or break into pieces and add to roasted brussel sprouts. Drizzle the entire dish with the remaining glaze.
