--------  ------------  --------------------------------
   6 1/2  cups          fresh orange juice -- from
                        blood oranges
   3      envelopes     unflavored gelatin -- 7g each
   2 1/2  cups          sugar

Preparation:

Strain the juice through a double layer of rinsed cheesecloth or a paper coffee filter. Soften the gelatin in 3 cups of the juice. Bring the remaining 3-1/2 cups of juice to a boil in a saucepan. Add the sugar and stir to dissolve. Remove from the heat as soon as it dissolves and stir inthe juice with the gelatin. Pour into a pretty glass bowl and allow to cool. Cover with plastic wrap and refrigerate overnight. Before serving, score deeply in a pattern of squares or diamonds. That way the gelatin stays pretty after you serve the first portions. Blood oranges become abundant in March and April. The juice makes this gelatin a beautiful red color, like strawerries. The recipe is written for quantity because it is such a great party dessert and it always creates a sensation. The gelatin can be made with other kinds of citrus juice. -- from Anna Tasca Lanza, The Flavors of Sicily (1996: ISBN 0-517-70079-4; Clarkson Potter, Pub.).
