Ingredients:

1 cup sugar
dash salt
1/2 cup half and half
1/2 cup lime juice (preferably fresh squeezed or fresh frozen, but reconstitued will do in a pinch)
2 eggs (whites)
bottle marichino cherries

     Combine 3/4 cup sugar, dash of salt, with 1 cup hot water in a pan. Bring to a boil, simmer 5 minutes. Cool. Add 1/2 cup half and half and 1/2 cup lime juice. Mix lightly and pour into bowl. Place in freezer until firm.
     Beat 2 egg whites to soft peaks, gently fold in the sugar and beat to stiff peaks. Break the first mix into chunks with wooden spoon. Beat with blender until smooth, keeping pan cold with a tray of ice beneath. Fold in egg whites. Lightly marble with maricho cherry juice (cherries optional). Return bowl quickly to freezer and freeze firm.

     This recipe serves six rational people, but it can easily be wiped out by two hooligans in nothing flat. Double the recipe if you feel the need to make more. Double it again if the need makes itself present. Beyond that, invest in a pad lock for the freezer.
