Serve this sweet, savory, and tangy onion jam accompanied by a cheese and/or charcuterie board or as a spread for sandwiches.

Caramelized Onion Jam

Heat a large, skillet over medium-high heat. Add butter and canola oil to hot pan. Once butter has melted, add onions, cayenne, salt, and pepper. Saute for 10 minutes, or until onions have softened. 

Reduce the heat to medium-low and cook for 40 minutes, stirring occasionally until the onions are browned and caramelized.

Stir in the balsamic vinegar and cook an additional 10 minutes. Remove from the heat; transfer to a serving bowl and cool to room temperature.
