This delicious glaze is the balsamic reduction that saves you one ruined pan from trying make it yourself. The Story Balsamic vinegar was a regional Italian specialty until about thirty years ago when it irreversibly swept the nation, altering our notion of vinegar for all eternity. No longer will vinegar live only as a mere preservative, ingredient, or home-remedy: we now drizzle it over our desserts and stir it into our cocktails. Where would our notion of a complete list of salad dressing options, or our image of white space on a restaurant appetizer plate, be without our now beloved balsamic vinegar?
