It may sound like I am being picky about terms but I am not..You cold smoked your sausage. This imparted the good smoke flavor to the meat. You then decided because of your equipment and process that you wanted to freeze it until you felt you can finish it. I see no problem with that. Now you want to Finish it. Finishing means just that. You are finishing the process of bringing it to a sausage quality stage.Please let me say how I would proceed after the meat has been slowly thawed and handled with care. I would either put it in the smokehouse ( or whatever you use ) or water that has been heated to about 180 degrees. Whichever you choose keep temp of water about 180 degrees ( or smoke house without smoke ) and the meat reaches internal temp of about 165 degrees. (lower if you are making ring Bologna ). Remove , chill down to about 110 degrees. Pat dry , allow to hang at room temp about an hour. This is called booming. It is mostly cosmetic but it does allow the meat filling to stabilize. Much like letting a roast or steak or even turkey sit before carving or serving. I would let it age in fridge for a few hours. Now comes the cooking process ( separate and distinct from the sausage making process ) If you want to impart more smoke flavor , do so however you are no longer smoking it , you are smoke cooking it. Hot smoking is a term I do not use.I make my sausage then I cook it. Depends on how I want it. Simmered in sauerkraut , grilled outdoors on a grill with or without a little more smoke added at the side of the grill , fried with onions , etc. After the curing , smoking and finishing process ( and after it blooms and ages ) temperature is no longer critical. You cook it the way you like it. Or you can ignore what i said and do it your way. Thats whats great about doing it ourselves.Happy sausage making Weisswurst. Merry Christmas to all.!!!
