What You Will Need

- coconut sugar – option to sub this with regular sugar, if you prefer.
- balsamic vinegar – these flavors really compliment the caramelized onions well!
- lemon zest – a little acidity always helps to bring out all of the great flavors.
- kosher salt – just a pinch for some added seasoning.

How To Make Onion Jam
You can begin by slicing and quartering your onions.
Next, heat up the olive oil in a cast iron skillet.
Place your onion slices in the hot cast iron skillet to begin the caramelization process.
You will want to let them cook for about 15-20 minutes. They will turn a nice brown color.
Now you can add the coconut sugar and let it melt before mixing it around.
Once the sugar has melted you can stir and cook for another 5-6 minutes and then add the rest of the ingredients.
