4 cups beef broth
1 onion (large, chopped)
1/4 cup red wine (or white)
2 tablespoons flour
2 slices French bread
3 tablespoons butter
1 teaspoon Sherry vinegar
1 pinch sugar
1 bay leaf
cheese (to taste, shredded, mixture of Parmeggiano Regiano and Cheddar, or Gruyere Cheese)

1 Melt 1 tablespoon butter in a medium pot over medium-high heat. Stir in chopped onion, season with salt, cover the pot and sauté the onion for a couple of minutes. Then add a pinch of sugar, reduce heat to real low and cook for about 25-30 minutes, until well browned but not burnt (stir every few minutes).

3 Gradually whisk in the wine and beef broth, stirring constantly. Add bay leaf, season with salt and pepper to taste, and cook for 10 more minutes.
