Melt 1 tablespoon unsalted butter in a pan.
Add in 1 tablespoon olive oil and mix it together.
Add in 1 1/2 peeled and chopped onions.
Cook down the onions until they are fully caramelized.
Add in 2 cups chopped figs, 1/2 cup honey, 1/2 cup sugar, and 1/2 teaspoon pumpkin pie spice. Mix all of it together.
Cook until the ingredients begin to cook down and simmer.
Add in 1/4 teaspoon sea salt and 1/4 teaspoon cracked black pepper. Cook entire mixture for about 30 minutes.
Once it's done cooking down, work in 1 tablespoon balsamic vinegar and then turn off the heat.
Once it has cooled, give it a taste as it might need more vinegar. If so, then add in a little bit more vinegar.
There you go...a delicious fig and onion jam.
