Strawberry Rhubarb Sauce
4 cups cranberry or pomegranate juice
2 bags frozen unsweetened strawberries
2 bags frozen unsweetened sliced rhubarb
1 cup good quality strawberry or black currant jam
1/4 cup kuzu, arrowroot or cornstarch (Passover: potato starch), dissolved in a little cold water in a small bowl until smooth
Bring all but last ingredient to boil in a medium pot. Reduce flame to low and cook 5 more minutes. Add starch mixture and cook only till mixture begins to boils and looks clear (a minute or two). The mixture will be chunky. If you like it smooth, cream it with an immersion blender. Wait until the mixture cools, then store in glass jars in the refrigerator.
