Heat all in a sauce pan on low for approx. 30 min, whisking while heating. The honey and mustard I start with a 1/4 cup and than just add by taste. It usually ends up somewhere less than 1/2 a cup. The pepper flakes are the kind you would sprinkle on pizza. I smash them so piece doesn't get stuck in a judges teeth and starts to burn. I use about 1/2 to 3/4 cup of finished sauce to a 6 lb. Pulled butt.
