According to the cooking instructions for fresh kielbasa posted on the website for Stanley Market's, there is very little boiling of the actual kielbasa during preparation. Instead the water is boiled in order to prepare the seasonings, and then the kielbasa is simmered in the seasoned water for the remaining cooking time.
- Season the water
Add enough water to a saucepan to cover the kielbasa completely. Add spices and other seasonings to the water, and then bring the mixture to a rolling boil. Common seasonings include onions, garlic or beer.
- Add the kielbasa
Add the kielbasa to the boiling water in the saucepan. The addition of the kielbasa lowers the water's temperature slightly. Wait until the water returns to a rolling boil, and then lower the temperature of the stove until the water is only at a simmer. Cook the kielbasa in the simmering water for 30 to 40 minutes, or until the internal temperature of the sausages reaches 165 degrees Fahrenheit.
- Continue cooking the kielbasa
Continue cooking the kielbasa up to a 50-minute total cooking time in order to increase tenderness. Remove the saucepan from the heat source once it reaches the desired tenderness level, and then remove the sausages from the water immediately. This prevents further cooking, which can cause the flavor of the sausage to cook out.
