The easiest thing to do is to cool the soup and then scoop off the fat crust with a spoon. Or vice versa: put the pot on the heat on one side, then the fat will collect near the opposite edge. It is also collected with a spoon.
We have collected simple methods on culinary forums to collect fat from soup, stew or gravy.
You can remove excess fat from soup or broth with a very cold ladle
Pitcher or sauceboat. When the soup has cooled down a bit, pour it into a pitcher or sauceboat. Now pour it back into the pot. Some of the fat will remain on the walls of the pitcher.
Any bread. Place slices of bread on the surface of the soup and press down with a spoon. The fat will be absorbed.
Cold spoon or metal ladle. Cool them and dip them into the soup. The fat will rise to the spoon itself. This procedure can be repeated several times.
Ice. Put a few cubes in the broth. After that, the fat around the ice should collect in large drops, collect them with a spoon, along with the ice.
Towel and ice. Ice cubes can be wrapped in a clean kitchen towel and moved over the surface of the soup. The ice will attract fat to itself.
