Dice the uncooked bacon up and cook over medium heat until the fat renders out and the bacon gets some color.
Once the bacon has taken on some color, but is not crisp, pour off all but about 2 -3 tablespoons of the bacon fat.
Add the onions and the 1/4 teaspoon of kosher salt. Lower heat to med-low and slowly cook the onions until they have reduced in size and darkened in color.
Let the onion mix cool and mix the rest of the ingredients together.
