For the Bacon Jam:
- Add the chopped bacon to a Dutch oven or other heavy bottom pot. Set over medium-high heat and cook the bacon until brown and crisp, stirring occasionally.
- Drain all but one tablespoon of the bacon grease from the pan, then add the butter and onions. Cook, stirring occasionally, 10-15 minutes or until the onions are softened and just starting to caramelize.
- Add the bourbon to the pot scraping any browned bits from the bottom of the pan. Add the honey, then turn the heat up to high and bring the mixture to a boil. Boil about 2 minutes, stirring often. Add the vinegar and boil for another minute.
- Add the bacon back to the pot, reduce heat to medium-low, and continue to cook 6-8 minutes, or until the mixture is thickened and dark.
For the burgers:
- Mix together salt, pepper, and garlic powder in a small bowl, sprinkle both sides of the burger patties with the seasoning mixture.
- Heat a pan over medium-high heat and add oil. Place the patties in the pan and cook for about 3 minutes. Flip and cook for an additional 2-3 minutes or until internal temperature reaches desired doneness. Place a slice of Munster on the burgers for the last minute and cover with a lid to allow it to melt. Remove the burgers.
- Slather each bun with mayonnaise. Layer with lettuce, the burger patty, and bacon jam.
- Enjoy!
