milk shake

A milkshake is a sweet, cold beverage which is usually made from milk, ice cream, or iced milk, and flavorings or sweeteners such as butterscotch, caramel sauce, chocolate sauce, or fruit syrup. Outside the United States, milkshakes using ice cream or iced milk are sometimes called a thick milkshake or thick shake or in New England (outside of Rhode Island) a frappe, to differentiate them from thinner forms of flavored milk.
