Ingredients:
- 2 to 3 strips bacon
- 1 tablespoon mustard seed
- 1/2 cup apple cider vinegar
- 1 1/2 pounds Vidalia onions, diced (about 5 onions)
- 1/2 cup light brown sugar
- 1/4 cup cane syrup
Preheat oven to 350 degrees. Lay the bacon onto a baking sheet lined with parchment paper and cook for 20 to 25 minutes, until each strip is evenly crispy. Remove and chop the bacon into small pieces. Set aside.
Toast the mustard seeds in a dry pot over medium heat just until the seeds begin to dance and get slightly browned. Add the vinegar and remaining ingredients (including the bacon) to the pot. Cover and raise the temperature to medium-high.
Allow the onions to sweat on the heat for about 20 minutes, stirring the pot a few times throughout. After 20 minutes, remove the cover and continue to cook on medium heat until most of the liquid is reduced and the onions are dark in color, approximately 45 minutes to one hour.
Marmalade will last for 2 weeks in the refrigerator and 3 months in the freezer.
Makes 6 cups.
