On my first visit to a fancy restaurant in Modena they gave me a free dessert: Vanilla ice cream with 25-year-old balsamic vinegar on it. The thought sounded repulsive, but that gooey, viscous stuff was amazing - like strawberry syrup only better. Then they gave me a small sample bottle to take home. This was 20 years ago and I still have never once since bought that yucky, watery, un-aged balsamic. Like wine and cigars - knowledge makes your life more expensive.
So, in addition to being a Connecticut pizza snob, guess I'm also a balsamic vinegar snob. Go figure...
