In Rhode Island, baked stuffed clams are called "stuffies." This recipe is extra-savory, thanks to the addition of the Portuguese smoke-cured pork sausage linguica, which is flavored with garlic and paprika. It is very popular in Rhode Island and other New England states, long home to Portuguese communities.
Swiss chard, a member of the beet family, has bumpy, dark-green leaves and white or red stalks and veins. We use green chard with white stems in this recipe since the bright red stems often bleed their color.
