Slow-cooked red onions

Side Serves 4 1h
You can also use shallots or white onions for this as well, but red will give the sweetest results. Slow-cooking brings out the natural sugar in onions; use them in everything from risottos, pasta sauces and pizza toppings to soups, stocks, and stews. They also make a good accompaniment to fish and meat.
