These are the most wonderful tasting onions I have ever had You'll never stand at the stove again once you've made these. If you can get Vidalia Onions there the best, If not any sweet onion will do. It's almost impossible to overcook this, so go for the deepest brown. Use the onions and liquid to flavor soup, stock and stews. They make wonderful additions to risotto, a perfect pasta sauce, and the world's best pizza topping (first drain off the liquid). Onions can be stored in zippered plastic bags in the refrigerator up to 2 weeks, or in the freezer up to a year. If you try these please rate it.
