What is Onion Jam?

It transforms humble onions into a rich spread that can elevate everything from sandwiches to cheese platters.
The slow caramelization process enhances the natural sweetness of the onions, resulting in a jam that is both complex and satisfying.
Ingredients for a Flavorful Spread
The key to a successful onion jam lies in the quality of its ingredients.
