For the Bacon:
Preheat oven 500 degree F.
Place 10 slice bacon on a parchment lined baking sheet lengthwise, pull bacon to stretch about half its original length (this helps with shrinkage during the cooking process) don't allow bacon to go over sheet pan edges
In a small bowl add, mustard, blackberry jam, hoisin sauce, and 2 tablespoon brown sugar, stir to combine
Spoon about 1 teaspoon of jam mixture over each piece of bacon, using a basting brush spread the jam mixture to coat the entire side of bacon, flip bacon over and repeat this process.
To cook, cover the bacon with an additional sheet/baking pan laying the bottom of the pan directly on top of the bacon
Place pans in oven and par-cook bacon for 5-6 minutes or until hot and bubbling but not browned
Remove from oven and set aside until ready to use
Reduce oven heat to 400 degrees F.
Brown remaining bacon slices and crumble for garnish
