18. You try to rush the cooking of caramelized onions.
Result: You end up with sautéed onions, which are nice but a far cry from the melt-in-your-mouth caramelized ideal.
If you want real, true, sweet, creamy caramelized onions to top your burger or pizza, cook them over medium-low to low heat for a long time, maybe up to an hour. If you crank the heat and try to speed up the process, you’ll get a different product―onions that may be crisp-tender and nicely browned but lacking that characteristic translucence and meltingly tender quality you want.
Bottom line: Know that caramelized onions take time, and plan to cook them when you can give them the time they need.
