ICE CREAM COOKBOOK

Frosteds are super sodas. First mix syrup with a small amount of ice cream
and then add soda water to fill the glass. Carefully spoon several
spoonfuls of the same flavor of ice cream as the syrup around the top of
the glass to make a cover for the glass. Then spoon vanilla ice cream on
top of it and finish it off with whipped cream and a cherry. What you have
done is covered the soda. It is frosted.
