Raspberries are pureed and strained, then the mixture is partially frozen, and, finally, the slush is served in sugar-rimmed glasses. If you prepare the dessert ahead and freeze the mixture until hard, defrost it in the refrigerator for an hour or so before serving, to achieve the desired silky consistency.
Individually quick frozen (IQF) berries, available year-round at most supermarkets, are generally of high quality and have been picked at the peak of ripeness and frozen without sugar. If fresh raspberries are in season, of course, you can use them.
* 1 12-ounce package IQF frozen unsweetened raspberries, defrosted, or 12 ounces fresh raspberries
* 1/3 cup seedless black raspberry preserves
* 1/4 cup water
* 2 teaspoons fresh lime juice
* 1 tablespoon sugar
* 4 fresh mint sprigs
Push the raspberries and preserves through a food mill, then strain through a fine-mesh strainer set over a stainless steel bowl to eliminate any remaining seeds. Or puree the berries with the preserves in a food processor, then strain through a fine-mesh strainer into a bowl. Add the water and mix well. (You should have about 2 cups.)
Place the bowl in the freezer and freeze, stirring every hour or so, until it is half frozen and velvety.
Meanwhile, pour the lime juice into one small saucer and put the sugar in another. Dip the rims of four stemmed glasses (preferably tulip champagne glasses) into the lime juice and then into the sugar, to create a border. Place the glasses in the freezer or refrigerator until serving time.
At serving time, divide the raspberry velvet among the prepared glasses and decorate each with a sprig of mint. Serve immediately.
