Hi Moss54 and Welcome to the Forum. If I understand you correctly you need a container to poach sausage in? I have used a large stock pot on the oven as well as a turkey Roaster, actually any roasting pan will work. Add water and heat to 80'c (175'F) and keep a thermometer in the water. Has worked for me very well, just keep water temperature above 70'c and don't go over 80'c and you cook your sausage without bursting the casing or boiling the fat out of the meat.
