2 cups fresh blueberries, rinsed and drained
1 cup lemon juice
1 cup white sugar
2 eggs, beaten
1 (16 ounce) bottle lemon-lime flavored carbonated beverage
1 cup ice
In a large saucepan, combine blueberries and lemon juice. Bring to a boil, reduce heat, and simmer for 20 minutes. Remove from heat, and stir in sugar.
Beat eggs, one at a time, in an electric mixer bowl until fluffy. Gradually pour into blueberry mixture.
Stir lemon-lime soda into blueberry mixture. Pour over ice, and chill in refrigerator. Serve at room temperature.
