Directions:

Drain the pineapple, reserving 2 tablespoons juice; set pineapple aside. Pour the juice into the top of a double boiler; add egg yolks, sugar, vinegar, butter and salt. Cook and stir over medium heat until mixture thickens and coats the back of a spoon. Cool. Stir in pineapple, three oranges, 2 1/2 cups grapes and marshmallows. Cover and chill for at least 12 hours. Fold in whipped cream just before serving. Top with remaining oranges and grapes.
