Ingredients
 
 

  • 1/2 stick (56 grams) unsalted butter
  • 2 large yellow onions , peeled, cut in half and thinly sliced (or diced if you prefer smaller pieces)
  • 2 teaspoons sugar
  • 1/2 cup red wine
  • 2 sprigs fresh thyme
  • 1 large sprig fresh sage
  • 2 cups strong beef broth
  • 1 teaspoon Worcestershire sauce

  • 1/2 teaspoon prepared yellow mustard
  • 1/4 teaspoon freshly ground black pepper
  • 1 tablespoon dark balsamic vinegar
  • 1 tablespoon cornstarch dissolved in 1 tablespoon water

  • Melt the butter in a saucepan over medium high heat. Add the sliced onions and sugar and cook for about 30 minutes until caramelized (deep golden). Add the red wine and herbs, bring to a rapid boil for 2 minutes, reduce the heat and simmer for 10 minutes.
