Also called kielbasy or Polish sausage, this smoked sausage is usually made of pork, though beef can also be added. It comes in chunky (about 2 inches in diameter) links and is usually sold precooked, though an occasional butcher will sell it fresh. Kielbasa can be served separately or cut into pieces as part of a dish. Even the precooked kielbasa tastes better when heated. See also sausage.
