How do you say whisk in Spanish?

Do you know that there is no word for 'whisk' in Spanish? How do the Spanish chefs do it then? What do they ask for when they bitch out their apprentices to "Hey, bone-head! go get that thing that we use to make the Hollandaise sauce get all frothy and stop from coagulating that you hold in your hand and make go real fast around and around! Now!"

So my students tell me, but there must be a name, Si?
