A glaze of ginger ale, cranberry and orange juices sweeten this Rosh Hashanah potato casserole, which can be assembled a day or two before. I prefer the addition of dried apricots and raisins but dried prunes are traditional. Canned mandarin orange segments or cubed canned pineapple would also be a nice change. Although Tzimmes is typically served at Rosh Hashanah, it is welcome at almost any Jewish festive meal.
