Note

Storage: This marmalade can be made up to 2 days ahead. Store covered in the refrigerator for up to 1 week. Reheat gently before serving.

Variations: Substitute balsamic vinegar for red wine vinegar for a deeper flavor profile. You can also add fresh thyme or bay leaves during cooking for an herbal note.

Safety: Ensure the liquid evaporates fully before serving to achieve the proper jam-like consistency.

Tips: Use a wide pan to allow moisture to escape faster, speeding up the caramelization process.
