Plum tomato jam is a sweet and tangy spread made with ripe plum tomatoes. It is a versatile condiment that can be enjoyed with bread, crackers, or used as a glaze for meats and vegetables. This homemade jam is easy to make and does not require pectin. The plum tomatoes are cooked down with sugar and spices until they reach a thick and jam-like consistency. The result is a delicious jam with a perfect balance of sweetness and acidity.
