What Is Onion Jam Made Of?
Onion jam is made of caramelized onions cooked with sugar, vinegar, and spices such as thyme, bay leaves, and black pepper. Some recipes may also include additional ingredients such as balsamic vinegar, honey, or red wine. The mixture is cooked down until it reaches a thick, jam-like consistency, and can be used as a condiment for sandwiches, burgers, or served alongside cheese and crackers.
