A popular party drink of oolong tea mixed with cranberry juice, soda and topped with ice cream. In the United States, an "ice cream soda" typically refers to the drink containing soda water, syrup, and ice cream, whereas a "float" is generally ice cream in a soft drink (usually root beer). Put two scoops of vanilla ice cream in a 12-ounce glass. Pour the tea over it (you can let the tea cool to room temperature or chill overnight in the refrigerator). Top with whipped cream and a maraschino cherry.
