There is a fine line between impeccable caramelized onions and burnt mess. However, if you're in need of a last ditch effort, there is a way to save almost overdone caramelized onions — ice.

If you notice the onions cooking to long, don’t just take them off the heat, instead throw an ice cube in the pan. The heat will quickly turn the frozen water into vapor and rescue your onions from their seemingly inevitable plight.

Please remember, this is not for already burnt onions but onions on the verge. If you want to save time and your patience, you can buy foods with caramelized onions already in them.
