Ice Cream for You
We like to eat ice cream. Ice cream is sweet, smooth, and cold. Do you know how ice cream is made?
collecting Milk The main ingredient in ice cream is milk. Mik comes from cows. Milking machines collect the milk from the cows. The machines pump the milk into a tank. The tank keeps the milk cooluntil it can be collected from the farm.
A large truck collects the milk from the farm. This refrigerated truck is called a tanker. The tanker keeps the milk cool on the wayto the factory.
Making Ice Cream At the factory, milk is mixed with sugarto make an ice cream mixture. The mixture is quickly heated and cooled to killany germs that are in the milk. Then the mixture is stirredto get rid of lumps.
Flavors and colors are added. Fruits, nuts, and candy can be added, too. The ice cream is then put into tubs. The tubs of ice cream are put into a freezerto harden.
