This is an easy reduction sauce that goes great with read meat and even pork tenderloin!
In a small saucepan, bring the balsamic vinegar to a simmer and reduce by 2/3. One chunk at a time, swirl in the butter and combine until it's completely melted, and the sauce has a smooth, velvety consistency. Serve immediately over chateubriand or other red meat. Delicious!
