Stovetop Method

1. Select a pot large enough to hold the ring or rings that you plan to cook. Fill it halfway with water, and bring it to a boil on the stovetop.

2. Turn down the heat, so the water is barely simmering, and gently lower your venison ring into it. The water temperature should ideally be no higher than 180 degrees Fahrenheit.

3. Simmer the ring or rings for 15 to 20 minutes, until an instant-read thermometer inserted horizontally into the end of the ring shows an internal temperature of 160 F.

4. Remove the bologna from the water with tongs or a slotted spoon, and drain it on several layers of clean paper towels. Once fully cooled, the bologna can be sliced and served cold, reheated or wrapped for refrigeration and freezing.

Slow-Cooker Method

1. Preheat your slow cooker on its High setting, and pour in enough boiling water to fill it halfway.

2. Nestle one or more bologna rings into the water. If your slow cooker is round, rather than oblong, you might need to snip the string that ties the bologna's ends together and gently bend it into a more circular shape.

3. Test the sausage with an instant-read thermometer after 15 to 20 minutes, raising one end from the slow cooker with a pair of tongs and inserting the thermometer horizontally. The sausage must reach an internal temperature of 160 F. If it's not ready yet, return it to the water and test again in another 5 to 10 minutes.

4. Lift the sausage from your slow cooker with a pair of tongs, setting it to drain on a plate lined with several layers of paper towels. Allow the sausage to cool completely before cutting or packaging it.

Large-Quantity Oven Method

1. Preheat your oven to 300 or 325 F. Arrange six to 10 bologna rings in a large roasting pan, and boil enough water to cover them. This might take several quarts, so use a large pot.

2. Open your oven door and place the roaster pan containing the sausages on a rack, with just the end of the roaster sticking out. Slowly and carefully, pour the boiling water into the roaster. If the large pot is unwieldy, use a smaller pot or large heatproof measuring cup as a ladle. This is awkward, but the alternative -- trying to maneuver the large roaster filled with water -- creates a high risk of scalding yourself with splashes and spills.

3. Slide the roaster the rest of the way into your oven, and close the door. Poach your sausages in the oven's diffuse heat for 20 minutes.

4. Slide the roaster back to the front of its shelf, taking care not to spill any water, and lift the end of one bologna ring from the pan. Test it by inserting an instant-read thermometer horizontally into the end of the sausage, so it's in the approximate middle. When the internal temperature reads 160 F, the sausage is finished.

5. Lift the sausages from your roasting pan with a pair of tongs, and transfer them to a colander or a large plate lined with paper towels. If you have additional rings to poach, refill the roaster and repeat the process. When you're finished, remove the roaster carefully from your oven and pour the hot water down the drain.
