If you have some seafood in the shell, discard the shells then cook them on a soft boil for 15 minutes.
These shells will make great stock to add to the soup.
Saute the onion in oil until tender and beginning to brown.
Add the jalapeno and garlic for 2 minutes to soften.
Add the tomatoes and seasonings, and then stir. Then add the wine.
Add the stocks, tomato paste and bay leaf.
Simmer for 10 minutes, adjusting the seasonings if need be.
Add the seafood, adding the most dense items first.
Cook for a minute or two and then add the smallest sizes last until everything is cooked through.
Serve the soup with crusty bread, savoring the wonderfully fresh flavors.
