2 ounces Bacon grease
1/4 pound Red onion, dice fine
2 C. Water
1/2 C. Honey
1/2 C. Red wine vinegar
2 T. Dijon mustard
1 1/2 T. Cornstarch
1 T. Tabasco (optional)

Place the bacon grease in a saucepan over medium−high heat. Add the onions and sauté until the onions start to blacken. While the onions are caramelizing, in a mixing bowl place the water, honey, pepper sauce, and red wine vinegar. Using a wire whisk, mix the ingredients well.
Add the cornstarch and whisk well. After the onions have caramelized, add the Dijon mustard to the onions and stir together with a rubber spatula. Add the water, vinegar, pepper sauce honey and cornstarch to the mustard and onions and mix. Continue stirring until mix thickens and comes to a boil. Remove from heat and store in refrigerator until needed. To reheat use a double boiler.
