 Well, it is a little bit uncommon. Usually you would add to an American buttercream, you might add two or three tablespoons. But I really wanted to incorporate a lot of heavy cream so that it would kind of get that lush, creamy texture and flavor. So I was able to get an entire cup of heavy cream into this buttercream. And I think you can really taste that and feel it in the silkiness of the buttercream. Now, you said you use a whisk or a paddle, a whisk to whisk it in a stand mixer. Is that right?
