Grape sherbet ice cream recipe

Grape flavored sherbet. This one is the coldest, most refreshing treat I've ever found for a hot summer day.
Whisk 1 egg* in a bowl and add 1 can sweetened condensed milk. When thoroughly mixed, add 1/2 cup heavy
whipping cream. Take a 2 litre bottle of grape soda and shake it carefully until all the "fizz" is gone and add it to
the mix. Chill completely in the refrigerator before freezing, then freeze in your ice cream freezer.
*If you are concerned about the possibility of Salmonella from uncooked eggs, substitute an equivalent amount of
Egg Beaters.
