You will need two large saucepots. In one pot saute one onion and half the garlic in 2 to 3 tablespoons extra-virgin olive oil until transparent. Cut Portuguese chourico into desired pieces, and add 1 pound to the onion mixture. Add 3 tablespoons crushed red pepper in vinegar.
Do the same exact thing in the other large saucepot.
To one pot, add 4 cups water, 1 can of tomatoes, ketchup, Portuguese allspice, if using, and chopped parsley. Let simmer for about 10 minutes.
Add potatoes, skins on, cut in desired pieces. When potatoes are almost cooked, add fresh green beans or pea pods. Do not overcook the beans or peas unless you like overdone vegetables.
To the other pot, add the remaining tomatoes, and wine or vermouth. Add lobster tails, clams, mussels, and fish. Steam until the shellfish opens and serve together with the stew.
