This is the most beautiful fish soup recipe – it hails from Provence, France – which uses the bones and, sometimes, the head of the fish. It’s easy to forget when you buy an expensive fillet of fish that there’s a whole head and skeleton going to waste, and there is so much good meat left on those bones. This recipe also reminds us that, as years go by, we need to remember the lessons from the past and use food in a way that respects both the beast and the earth.
