Patience is a Virtue:

Caramelizing onions takes patience. You will be tempted to speed the the process along by turning up the heat. All that accomplishes is burning the onions. Allow the onions to cook at medium heat until they begin to brown and reduce in size, this can take 20-25 minutes or so. Stir frequently.

Last But Not Least:

As the liquid in the onions begins to evaporate, the onions will get sweeter and sweeter because the natural sugars in the onions get more and more concentrated. Once the onions have lost about half their volume, sprinkle with sea salt and freshly turned pepper, then drizzle with balsamic glaze.. Balsamic glaze is a reduced balsamic vinegar and has the consistency of a thick syrup. It is the perfect addition to caramelized onions!

    Caramelized onions add so much flavor to any dish/sandwich/wrap/pie. (Okay, maybe not pie) Only downside is I wish it didn’t take them thaaaat long to make.
