Method

  • To make the soup base, combine the water, tomatoes, wine, leeks, carrots, onion, thyme, lemon zest, and saffron in a saucepan and bring to a boil.
  • Lower the heat to a lively simmer and cook until reduced by about one third, about 45 minutes.
  • Stir in 1/4 cup olive oil, season the mixture lightly with salt, and continue to simmer until the liquid portion of the soup base is reduced to about 8 cups, about 20 minutes.
  • Strain the soup base into a 3-quart saucepan and keep it warm over low heat.
  • Discard the solids.
  • (The soup base may be prepared up to 3 days in advance and refrigerated.)
  • If you have prepared the soup base in advance, bring it to a simmer in a medium saucepan.
  • Adjust the heat to very low and keep warm.
  • Heat 1/4 cup olive oil in a large (about 8-quart), heavy pot over medium heat.
  • Add the garlic, leeks, and onion and cook, stirring, until the onion is wilted but still crunchy, about 4 minutes.
  • Add the calamari and cook, stirring, until they turn opaque, about 2 minutes.
  • Pour in all but 1 cup of the hot soup base and bring to a boil.
  • Stir in the scallops, fish fillets, and beans, if using.
  • Adjust the heat to simmering and cook until the seafood is barely opaque at the center, about 5 minutes.
  • Meanwhile, add the mussels to the soup base remaining in the saucepan.
  • Increase the heat to high, cover the saucepan, and steam over medium heat, shaking the pan occasionally, until the mussels open, about 3 minutes.
  • Stir the shrimp, parsley, and steamed mussels into the large pot of soup.
  • Simmer until the shrimp is cooked through, about 1 minute.
  • Check the seasoning, adding salt, if necessary, and pepper.
  • Ladle into warm soup bowls, passing a basket of the bread of your choice separately.
