Balsamic-Glazed Red Onions
A road trip Mary Ellen Carroll took with her grandfather inspired this sweet red-onion condiment. You'll know the onions are done when they are very tender and their juices are syrupy. Don't overcook the onions or the sweetness will be cloying. Carroll slathers any leftovers on slices of buttered baguette.
