Beating means to mix fast with a spoon, mixer, or fork to make a mixture smooth.
Get two eggs and cream of tartar as ingredients.
Crack both eggs in half and only put the egg whites in the bowl. Not the yolk!
Get the egg whites into the bowl.
Beat the egg whites until they turn white and when you take out the mixer there should be beaks.
Keep on mixing and add a sprinkle of cream of tartar.
This is how it should look like when you are done beating.
Make sure there are beaks at the end.
