I love cooked onions. They aren't something I always appreciated. It wasn't until I learned the slow are of caramelization. It's so time consuming, but so worth it.
The process is long because the sugars in the onions have to breakdown, thus caramelizing. You could speed up the process by adding brown sugar, but this is the real way to do it.
What you'll need:
Some olive oil
A good frying pan
Slice the onion in strips.
Tip: Slice your onion, removing the root, tip and skin and save these parts in a plastic bag in your freezer for use in future broths.
Coat your pan with olive oil and throw them in the pan.
Cover with the lid of the pan and let cook 30 - 60 minutes, stirring every few minutes to prevent sticking.
No, this isn't apples, it is caramelized onions!
