"This recipe is great!!! I altered it for a friend of mine who doesn't eat fowl or "meat." I used two cartons (32 oz. each) of vegetable stock instead of the chicken stock and chicken base. I would have used seafood sausage, but the store was out, so I just omitted the sausage altogether. I chose the Worcestershire sauce over the soy sauce and tasted it before the seafood was added and was NOT pleased--it tasted sour. But after I added the seafood, the sweetness of the shellfish and the briny juices "magically" corrected that sour taste and it was great!"
