Recipe Information
Ingredients
- 4 large yellow onions
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 tablespoons granulated sugar
- 2 tablespoons balsamic vinegar
- 1 tablespoon red wine vinegar
- 0.5 teaspoons salt
- 0.25 teaspoons black pepper (freshly ground)
Instructions
Peel and thinly slice the yellow onions into uniform slices to ensure even cooking.
Heat a large, heavy-bottomed skillet over medium heat and add the olive oil and butter. Allow the butter to melt completely.
Add the sliced onions to the skillet and stir to coat them evenly in the oil and butter mixture. Spread them out in an even layer.
Reduce the heat to medium-low and cook the onions, stirring occasionally, for about 25-30 minutes. Be patient as the onions slowly soften and caramelize. Adjust the heat if necessary to prevent burning.
Once the onions have turned golden brown and have a jam-like consistency, sprinkle the sugar over them and stir well.
Add the balsamic vinegar and red wine vinegar, stirring to deglaze the pan and incorporate the liquid into the onions.
Season the mixture with salt and freshly ground black pepper, adjusting to taste.
Continue cooking the marmalade for another 10 minutes, stirring frequently, until the mixture becomes thick and glossy.
Remove the skillet from heat and allow the marmalade to cool before transferring it to a glass jar or airtight container.
Store the marmalade in the refrigerator for up to one week. Serve it slightly warmed or at room temperature with your favorite dishes.
