Don't be scared off by the amount of olive oil in this recipe – you don't actually eat it, so almost all of it will be left once your meal is done. It's also incredibly flavorful, so go ahead any use it to season other dishes throughout the week. Serve this with a selection of pickles and olives to help cleanse your palate and balance out the fatty fish. It's the perfect excuse to visit your nearest grocery store's olive bar!
