What is the fluffy white topping on pies in bake shops?

Here's how to tell the difference:

* Whipped cream is made by whipping heavy cream until it becomes fluffy and light. It has a delicate, slightly sweet flavor.

* Meringue is made by whipping egg whites with sugar until they form stiff peaks. It has a slightly tangy flavor and can be either soft or stiff, depending on how long it is whipped.

If you're unsure, it's always best to ask the baker what topping they used.
