What are 3 examples of churn frozen desserts?
~ Ice Cream
~ Gelato
~ Sherbet
~ Sorbet
Define: Churn Frozen Dessert
A dessert is frozen while constantly being mixed usually with a machine.
What does the churning process prevent?
~ the mixture freezing into a solid block of ice
~ ice crystals from becoming too big
What is incorporated into the ice cream during the churning process?
Air
How does Granite differ from other churn frozen desserts?
Granite is not churned in a machine, rather it is placed in the freezer and stirred frequently. This produces a product with larger ice crystals and a much coarser texture.
Define: Overrun
The increase in the volume of frozen desserts because air is incorporated during freezing.
True or False - Greater overrun results in an ice cream that melts faster.
True
What is the desired amount of overrun in frozen desserts?
20% - 50% provides desirable texture and a smooth mouthfeel.
What are 3 quality factors of ice cream?

~ Overrun

False - the texture is better if an ice cream base is allowed to sit for 12 hours before freezing

The sitting time allows the egg and dairy proteins to bind to the water molecules in the base leaving fewer water molecules available for forming ice crystals in the final product.
