Here is another recipe from the Pure Sweet sugar bag. If you live where lemons grow plentifully and have access to lots of them this would be a handy recipe to use.
In a saucepan, mix water and sugar and boil for 5 minutes. Cool, then stire in combination of lemon juice and grated rind. Freeze, stirring occassionally. When almost set, scoop into serving deshies and return to freezer, or removed from freezer until desired softness to scoop into dishes. Makes 1 1/2 quarts.
I thought the lemon ice would be very festive if the ice were put into the lemon rind shells and frozen just like you do with orange sherbert or ice in orange rind cups.
