How to Make Red Onion Marmalade

  1. Peel and thinly slice 1 large red onion (about 2 cups).
  2. In a non-reactive saucepan, combine the sliced red onion, 1/2 cup apple cider vinegar, 1/2 cup granulated sugar, 1/4 cup brown sugar, 1 tablespoon Dijon mustard, 1 teaspoon salt, and 1/2 teaspoon black pepper.
  3. Bring the mixture to a boil over medium heat, stirring constantly.
  4. Reduce the heat to low, and simmer uncovered, stirring frequently, until the onions are tender and the mixture has thickened to a marmalade consistency (about 30-40 minutes). The cooking time will depend on the size of your slices and the desired thickness.
  5. Remove from heat and let cool completely.
  6. Transfer the marmalade to a clean, airtight container and refrigerate for at least 24 hours to allow the flavors to meld. It will keep for up to 3 weeks in the refrigerator.
