Sure, and this is why French cooking is fucking garbage. The only thing people can think that a hot 15-20 minute cook won't work for is Highly Sophisticated French Cooking. I don't make french onion soup because it's a humongous pain in the ass, and for pretty much anything else that you want a nice sweet mush onion for this is more than good enough. French food isn't meant to be cooked in a home kitchen by a home cook, it's too much work. Making a good French onion soup requires a ton of other work too, it takes hours to do properly. Who is doing that with any regularity that it's worth saying shit like ALL RECIPES THAT SAY IT TAKES LESS THAN 90 MINUTES TO CARAMILIZE AN ONION ARE WRONG
