Melt the butter in a small saucepan over medium heat. Add the garlic and saute for 30 to 45 seconds, but do not let it color. Add the balsamic vinegar - stand back a little as it can splatter up a bit. Bring the vinegar to a boil and reduce by half. Turn down the heat once it is reduced and stir in the remaining ingredients. Simmer for 5 minutes to allow the flavors to come together and then remove from the heat. Use immediately or store in the fridge in an airtight container for up to 1 week.
