Recipe Information
Ingredients
- 4 large (approximately 800g) red onions
- 2 tablespoons olive oil
- 100 grams brown sugar
- 70 milliliters balsamic vinegar
- 50 milliliters red wine vinegar
- 3 sprigs fresh thyme
- 0.5 teaspoons kosher salt
- 0.25 teaspoons black pepper
- 60 milliliters water
Instructions
Peel the red onions and slice them thinly into half-moons.
Heat the olive oil in a large, heavy-bottomed skillet or saucepan over medium heat.
Add the sliced red onions to the skillet and stir to coat them evenly in the olive oil. Cook on medium heat for 10-15 minutes, stirring occasionally, until the onions are softened and translucent.
Stir in the brown sugar and continue cooking for 5 minutes, allowing the sugar to dissolve and the onions to begin caramelizing.
Add the balsamic vinegar, red wine vinegar, water, thyme sprigs, salt, and pepper to the skillet. Stir everything together until well combined.
Reduce the heat to low and allow the mixture to simmer for 25-30 minutes, stirring occasionally. The liquid should reduce, and the mixture will thicken to a jam-like consistency.
Remove the thyme sprigs from the mixture and discard them.
Taste the jam and adjust the seasoning with additional salt or vinegar, if needed.
Let the red onion jam cool slightly, then transfer it to a clean, sterilized jar. Allow it to cool completely before sealing tightly with a lid.
The red onion jam can be stored in the refrigerator for up to 2 weeks. Serve at room temperature for best flavor.
