In a large heavy saucepan over medium-high heat , melt butter. Add bacon , onion and fennel and cook until bacon and onions start to brown.
Stir in diced potatoes and brown them slightly. (Turn heat down to medium if butter is getting too brown or burning).
Stir in flour and cook 1 minute. Add the bay leaf, and the clam juice from the can of clams and from the bottle. (This should just cover the potato mixture. If not, add a touch of water to cover). Bring to a simmer, cover, and simmer for about 10 minutes until potatoes are tender.
Remove lid and add milk and cream and bring back to a simmer. Add clams, all the seafood, corn and salt. Bring back to a simmer and cook about 5-10 minutes, until all the seafood is cooked through (but not overcooked).
Season with more salt and pepper to taste. Discard bay leaf. Serve hot, with a sprinkle of fresh parsley on top and warm bread on the side.
Enjoy!
