Part of the repertory of Craig Claiborne and Pierre Franey of the New York Times of leftover Thanksgiving Day foods includes an uncommonly refreshing dessert ice made with the inevitable, day-after cranberry sauce. It is an extremely easy dish to make, requiring only a simple syrup made with sugar and water, cooked for 5 minutes and chilled. This is blended in the food processor or blender with the slightly tangy, sour-sweet sauce, along with orange juice. The liquidy mixture is poured into the container of an ice-cream maker and frozen according to manufacturer's instructions. This will produce what is know in French as a granite or in Italian as a granita, which is to say frozen fruit and ice. It is velvety smooth and, with the addition of a little egg white or heavy cream before the mixture is frozen, can be turned into a delightful sherbet. (Prep time does not include freezing.)
