Soften the unflavored gelatin in 1 cup cold water. Set aside. Heat the juice and add the sugar. Make sure the sugar is dissolved (near boiling). Put the pineapple juice and gelatin together and put it into the fridge until set. When the gelatin is set, add 2 cups shredded cheese and 2 cups crushed pineapple. Fold in 2 cups whipped cream. Chill. Can be made a day ahead. Traditionally, slices are served on top of a lovely leaf of bib lettuce.
