What distinguishes frozen or regular custard from ice cream is that custard is made up of a minimum of 1.4 percent egg yolk and has varying consistency, whereas ice cream often does not contain eggs and is always thick.

Custard ranges from runny to thick or viscous, and always has milk or cream and egg yolk; custard is also mostly made of sugar, but it can be savory as well. Ice cream is made out of cream or milk and sugar in a traditional ice cream freezer, and usually does not contain egg.

Standard custard is cooked in a double boiler. The consistency of custard ranges from a thin pouring sauce to a thick pastry cream. Frozen custard is produced in a soft-serve ice cream maker, which introduces more air to the concoction than a traditional ice cream maker. The result is a dense but creamy consistency. Frozen custard may be served at 18 degrees.

Standard ice cream is made in an ice cream maker, whereas soft-serve receives more agitation. Standard ice cream is dense and creamy; soft-serve is fluffy and smooth. Ice cream is served at 10 degrees.


Standard custard comes in many variations. Egg is used to thicken a standard custard. However, a pastry cream results from adding starch. Adding a flavoring such as vanilla, chocolate, or lemon results in Crème pâtissière. If chefs add gelatin to the standard mixture, they have crème anglaise collée. All the basic ingredients of custard can be frozen in a soft-serve ice cream maker for frozen custard. Quiche is an example of a savory custard.
