Vanilla limeade sherbet ice cream recipe

We used to walk downtown to get a vanilla limeade at the local drugstore soda fountain. Mmmmm.
In a large mixing bowl, lightly whisk one egg*, and then whisk in 1 can Eagle Brand sweetened condensed milk.
Add one 2 litre bottle of 7-up (which has been shaken to remove the "fizz"), 1/2 cup whipping cream, and 1 1/2
tbsp vanilla extract. 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.
