I have done this before using a roaster. I put the sausage right in the water. Then brought to internal temperature i wanted.
Saves alot of time. And sausage come out good.

I’ve always used pork trimmings. I go to a local meat locker and purchase by the pound then grind with 3/16 plate. Or at grocery store buy ground pork without any spices or seasoning.
