Preparation
- Thinly slice the onions with a mandoline or a knife.
- In a large skillet, heat the butter and oil over medium-low heat. Add the onions and salt. Cook uncovered for 25 to 30 minutes, stirring often, until the onions are soft and deeply caramelized. If they brown too fast, lower the heat. If they stick, add a small splash of water.
- Pour in the rum and let reduce for 2 minutes, scraping the bottom of the skillet.
- Add the maple syrup, balsamic vinegar, thyme and bay leaf. Cook for 8 to 10 minutes over low heat, until the liquid is syrupy and a spoon leaves a trail in the skillet.
- Remove the thyme and bay leaf. Stir in the mustard, add pepper and taste. Adjust the salt as needed.
- Let cool slightly, then transfer to a clean jar.
