Red Gurnard Soup

Gurnard are cheap enough to buy just to make a soup, though this is also a great way to use up the bones from either of the other gurnard recipes. I hate throwing fish bones away, so I normally prepare a fish soup or stock straight away, or just freeze the bones if I haven’t time to do it there and then. You can use almost any fish bones for this recipe, except oily fish like mackerel and herring.
