1 quart lemon juice
8 drops red hot
1 teaspoon vanilla extract
8 cups milk
1 tablespoon lemon-lime flavored carbonated beverage
In a heavy machine cup or metal bowl, combine lemon juice, red hot and vanilla extract. Mix well and pour into plastic tub. Cover and refrigerate overnight at least one day, to allow for storage and blending.
While chilled, blend lemon-lime soda in 6 cups milk or 3/4 cup lemon-lime flavored carbonated beverage. Pour lemon-lime sugar mixture into glass of soda and toss to prevent leaks. Serve immediately.
