ingredients are soft.3Take the pot out, separate the juice from the
ingredients and pour the ingredients in a bowl, separate the bones and using a potato masher (gousht-coob) or something similar, finely mash the whole mixture.4Taste a small portion and add more salt/pepper if needed.5When the mixture has a smooth texture, it can be served.
