In a small sauce pan set over medium low heat.
Combine maple syrup, bourbon, dijon and stone ground mustards, hot sauce/cayenne pepper (if using) with a pinch of salt and pepper in a small sauce pan.
Whisk together to combine all ingredients. Reduce glaze until slightly thickened (about 5-10 minutes). Be careful to not burn because of the high sugar content.
