Ingredients
- 2 tablespoons olive oil
- 1 medium yellow onion, finely diced (about 1 1/2 cups)
- 1 pinch salt, plus more to taste
- 1 (28-ounce) can Muir Glen canned diced tomatoes
- 1 cup sugar
- 1 tablespoon white vinegar
Method
- Set a large (roughly 12-inch) skillet over medium heat. Add the olive oil, then chopped onion. Season with a pinch of salt. Saute, stirring occasionally, until soft, about 10 minutes.
- Add the tomatoes, sugar, and vinegar. Stir. Adjust the heat as needed to keep at a steady simmer and cook, stirring often, until the syrup is thick and dragging a spoon along the pan leaves a distinct trail (about 25 minutes). Transfer to a heat-proof container and refrigerate to cool completely.
