Mancini sells jarred "fried onions" that IMO should be called smothered. They are not at all brown. Someone once gave me a jar of delicious caramelized onion spread that was, I think, something they received as part of a Harry&David basket and did not want (fools!). Stonewall Farms has Roasted Garlic and Onion Jam that is mostly jelly, and sweeter than homemade caramelized onion.
Although caramelized onions are not hard to make, they do take time and monitoring, and prolonged heat. So they are not something I want to make during hot weather. (Don't tell me crockpot, please - it's still heat for a long time and for, IMO, an inferior result.)
I am surprised that caramelized onions don't seem to be commercially available in supermarkets. Or am I not looking in the right sections? I live in suburban Boston.
