For a richer flavor, consider using olive oil instead of vegetable oil. The type of onion you use will influence the final flavor profile. Yellow onions offer a good balance of sweetness and sharpness, while red onions will contribute a more vibrant color and slightly milder taste. Be careful not to burn the caramel. Keep a close eye on it as it cooks, and adjust the heat if necessary. The jam can be stored in an airtight container in the refrigerator for up to two weeks. The flavor will continue to develop over time.

Follow The Directions
01
Step
10 mins
In a heavy-bottomed skillet, heat the vegetable oil over medium heat. Add the sugar and, using a wooden spoon, stir constantly until the sugar melts and transforms into a light caramel color. Be patient and watch carefully, as this will take approximately 10 minutes. The mixture will be very hot, so exercise caution.
02
Step
15 mins
Introduce the coarsely chopped onions, salt, and black pepper to the caramelized sugar. Stir frequently, ensuring the onions are well coated. Continue to cook over medium heat, allowing the onions to slowly caramelize and soften, about 15 minutes.
03
Step
30 mins
Pour in the red wine vinegar, and bring the mixture to a gentle simmer. Allow it to cook, stirring occasionally, until the jam reaches a thickened, spreadable consistency. This will take around 30 minutes. Let the jam cool completely before serving to allow the flavors to meld and deepen.
