Mix fruits in a saucepan with Diät Gelier Traum 3:1 and bring to a boil over high heat, stirring, until the entire mixture is bubbling vigorously. Boil for 4 minutes until bubbly, stirring constantly. Remove the saucepan from the heat and quickly fill hot rinsed jars with the hot Diet Apricot Blueberry Jam to the brim and seal immediately.
