I found this somewhere and made it after the brisket I smoked over the weekend. It has a depth of flavor this is so good. I took the Burnt Ends and shredded them apart, heated them in the sauce, and put them in a grilled cheese using Pepperidge Farm Sourdough bread. I used Sharp Cheddar and American cheese and it was over the top good! Here is the recipe if any of you want to try it.
BRISKET SAUCE
1 cup of Brisket au jus
2 Cups Ketchup
1/4 cup freshly Squeezed Lemon Juice
1/4 cup freshly Squeezed Lime Juice
1/2 cup Bourbon
1/2 cup packed Brown Sugar
1 onion, small chop
1 Tablespoon Smoky Hungarian Paprika
1 Teaspoon Celery Salt
1/2 teaspoon ground red pepper
Add all ingredients and cover simmering 45 minutes to an Hour. Stirring so not to burn.
