Saves times and gives the sweet taste. If someone doesn’t want to do it for 45 minutes then yeah
But it keeps the the sour and bitter tastes in. Caramelizing replaces most of those with sweet.
Sour and bitter can be good though. I love fresh onion as is. I ghetto caramelize it a bit to make it more palatable to my girlfriend though. For that you don’t need to do a proper caramelization, getting the process going and adding a bit of sugar is enough.
I love to add vinegar too though. Vinegar, a bit of sugar, a bit of salt, some time on the pan, delish.
