Make Seafood Stock*: Use kitchen shears to cut open the crab legs and remove the meat, then place the cracked shells into a stock pot. Remove shells and tails from shrimp then add to the stockpot. Add enough water to the pot to cover the shells by about an inch. Add a pinch of salt. Cook over medium high heat until water reaches a bare simmer. Add clams and mussles on top (don’t stir) and cover pot. Cook for 2-3 minutes, until shells open up. Uncover, remove from heat and set aside

Tomato Base: Add oil to a large Dutch oven over medium heat. Stir in onion, fennel and 2 teaspoons kosher salt. Cook until onion is soft and translucent, 8-10 minutes. Stir in garlic and red pepper flakes then cook for 1 minute. Add tomato paste and stir well. Add wine and cook for 2 minutes. Stir in crushed tomatoes, bay leaf, and oregano.

Strain Stock: Set clams and mussels aside and strain seafood stock through a fine mesh strainer with a cheesecloth over it (if you don’t have a cheesecloth, just don’t add the bottom tablespoons of liquid, that may have sand in it) into a measuring cup. Add 4 cups seafood stock to the pot. Bring to a simmer, reduce heat, cover pot, and simmer for 30 minutes.

Add seafood: Just before you’re ready to serve the stew, bring to a simmer, stirring. Cut the fish into 1 inch pieces and drizzle fish and shrimp with a little oil, and season with salt and pepper. Add the fish, cover, reduce heat and simmer for 3 minutes. Stir in shrimp and crab and simmer about 2-3 minutes, just until shrimp are pink. Stir in steamed clams and mussels. Taste the sauce and add more seasoning, if needed. Sprinkle with fresh parsley.

Serve: Ladle stew into bowls and serve with fresh lemon wedges, crusty bread, and extra bowls for placing shells in (and lots of napkins)!
