Nobody Caramelizes Onions Right (What 45 Minutes on a Stove Actually Looks Like)

Every recipe you have read says ten minutes. Ten minutes gets you a softened onion, which is a perfectly decent thing and is not what you tasted on that burger or in that soup. I spent thirty-four years in professional kitchens and I never once saw a pan of onions come good in under an hour. So this is the whole thing, slowly, with the reasons attached. Why an onion cannot brown until its water is gone, and the three stages that happen in order whether you like it or not. Why you slice it pole to pole and never across. Why plain butter is the wrong fat for a long cook, and what to use instead. Why the width of your pan matters more than your stove does. When the salt goes in, when the lid comes off, and the two signals that tell you browning has finally started. What the brown film on the metal is and how to get it back into the pan. Then the finish almost nobody does at home, which is where good onions turn into restaurant onions. Three pounds, one afternoon, a week of eating well. The numbers: • Onions: 3 lb, about 6 large, sliced pole to pole at 1/8 inch (3 mm) • Fat: 2 Tbsp olive oil, clarified butter, or rendered fat. Butter's milk solids burn at 250 degrees Fahrenheit • Pan: the widest heavy pan you own, 12 inches or bigger. Surface area is speed • Salt: 1 teaspoon at the very start, to pull the water out • Stage one, lid on, medium-low: about 25 minutes, stirring every 5 or 6 minutes • Stage three, lid off, medium-low: 30 to 45 minutes, stirring often, deglazing 3 or 4 times • Total clock: 60 to 80 minutes for the real thing • Gastrique: 1/4 cup balsamic vinegar to 1 to 2 Tbsp dark brown sugar, adjusted by taste • Yield: 3 lb cooks down to roughly 1 1/2 cups • Storage: cooled flat to room temperature (3 to 4 hours), then about 5 days refrigerated, or frozen flat and dry
