Achieving Proper Caramelization Timing

Creating deeply caramelized onions requires patience and proper heat management for maximum flavor development in savory applications. Cook over medium-low heat for 45-50 minutes, stirring occasionally to prevent burning while allowing natural sugars to develop. Add brown sugar early to accelerate caramelization but avoid high heat which burns surface before interior breaks down. The onions should become deep golden brown and jammy in texture, concentrating flavors that complement rich bread and strong cheese. Finish with balsamic vinegar for acidity that cuts richness and adds complexity. Properly caramelized onions should be sweet, savory, and deeply flavored without any sharp raw onion bite.
