Tips & Substitutions
For a more robust flavor, consider adding a splash of white wine or a teaspoon of balsamic vinegar while cooking the onions. If you want a gluten-free option, substitute the flour mixture with cornstarch mixed with water. For added depth, sauté some garlic with the onions. Remember to stir the onions regularly to avoid burning and achieve that perfect caramelization.
