Burrida ( Italian Seafood Soup )

Burrida is a soup or stew made with seafood from the north of Italy around Liguria, and this type of cooking is right up my street, lots of garlic, tomatoes, seafood, what's not to like?!!
Now this recipe can be made quite quickly, cooking the sauce and then adding the fish in at the end just to cook through
But i think this dish benefits from a long cooking time to really develop the flavours
