1. Bring 1 1/2 inches of water to a boil in a large stockpot. Add lobsters, cover, and cook 13 minutes. Remove lobsters and cool just enough to handle. Crack shells and remove meat. Keep claws whole and chop remainder of meat into large pieces; reserve.

2. Preheat oven to 450 degrees. Heat a 12-inch ovenproof skillet or paella pan over medium-high. Add oil and saute onion and bell pepper until onion is translucent, about 5 minutes. Add linguica and cook 3 minutes. Gently stir in rice and cook a few minutes to lightly toast.

3. Add broth, saffron, and salt; bring to boil over high heat. Remove from heat, cover with a lid or sheet of foil, and place paella in oven for 10 minutes. Uncover; scatter clams on top of rice. Cover; cook until clams are open and liquid is absorbed, 15 minutes more, adding codfish and lobster in the last 3 minutes. Discard any clams that do not open. Garnish with parsley; serve.
