What is Freezer Jam?

Blueberry Raspberry Freezer Jam is a type of jam that is made by combining blueberries and raspberries with sugar and pectin. Unlike traditional jam recipes that require cooking, freezer jam is made by simply mixing the ingredients and allowing them to set in the refrigerator or freezer. This results in a jam that is fresher and more vibrant in flavor than cooked jams.
