The simplest way to get your broth clear is to skim your soup and keep your temperature at a simmer. You need to start skimming your soup with a spoon as soon as it comes up to a light boil and then turn down to a simmer. The gray unwanted stuff and oil that accumulates on the top of the soup’s surface can easily be removed with a spoon or ladle. If it is just a little oil, we have found using a paper towel to run around the top edges works like a charm.
