  RED ONION MARMALADE:
  
  (marmalade may be made up to 2 days ahead).
  
  3 tablespoons extra virgin olive oil
  10 cups red onions, thinly sliced
  1 tablespoon brown sugar
  to taste salt and white pepper
  3/4 cup red wine vinegar
  1 1/4 cups red wine
  
  
  Heat olive oil in a large heavy bottomed saucepan and add the onions. Cook over medium heat until they begin to soften, about 10 minutes, then add the brown sugar and stir to coat. Season with salt and pepper.
  Continue cooking over medium heat, stirring frequently, or bake in a 350 degree oven until the onions are golden soft and brown.
  Add the vinegar and cook until it has completely evaporated, then add the red wine stirring the onions frequently to prevent sticking and burning. When the red wine has evaporated, taste and adjust the seasoning. Remove from heat and keep warm
