From Saveur magazine, Nov 2008. These incredibly soft, rich tomatoes and onions are great smeared on a circle of pizza dough instead of tomato sauce. Melted tomatoes make a great base for sauces, and melted onions add depth to soups or stews.
- Place oil, salt and onions or tomatoes in a saucepan. Cut a circle of parchment paper which fits snugly inside the saucepan. Place parchment down on top of the cooking sauce. Cook very slowly, over a low flame, for several hours, until reduced in volume by 50%.
