Recipe information
Yield
Makes about 2 cups
Ingredients
1 tablespoon vegetable or canola oil
4 yellow onions, thinly sliced
1/2 teaspoon ground cloves
1 teaspoon salt
1 teaspoon freshly ground black pepper
3 tablespoons brown sugar
Zest from 1/2 orange
2/3 cup balsamic vinegar
Preparation
Step 1
Heat the oil over medium heat in a large skillet. Add the onions and cook, stirring occasionally, until they are soft and caramelized, about 20 minutes. Add the cloves, salt, and pepper, stirring to coat.
Step 2
Reduce the heat to medium-low and add the brown sugar and orange zest. Cook, stirring frequently, until the onions start to shrivel. Add the vinegar, reduce the heat to low, and cook for 1 1/2 hours, stirring occasionally. Adjust the seasoning to taste and serve warm. Leftovers can be stored in the refrigerator, tightly sealed, for about a week.
