A milkshake is a sweet, cold beverage which is made from milk, ice cream or iced milk, and sweet flavorings such as fruit syrup or chocolate sauce. Milkshake-like recipes which use yogurt, crushed ice, and fresh fruit and which are made without ice cream are usually called smoothies. There is nothing quite as refreshing and tasty as a tall, frothy milkshake on a hot summer afternoon. Four popular milkshake flavors are vanilla, chocolate, strawberry, and the black and white, made using vanilla ice cream and chocolate syrup.
