I don't have notes with me,but I'm guessing about 45 mins at 250�.
60 mins at 225�
Although we eat meats rare, to med rare,we don't focus on that with smoked ground meats.
We find that the low temps in the Cookshack leave even med cooked ground meats very moist.
We put a pan of sliced yellow onions under them and that is a nice compliment to salads,breads,etc.
They don't cook out a lot of grease/moisture.
They won't get that grilled brown,but brushing with a little Kitchen Bouquet,or soy sauce,will help.
The type of wood ,and the amount will ,affect it some.
I am reluctant to use much wood.
The wife is a CBJ and a comp cook and she says they get too smokey to be good.
We crumble chunks of ground beef and smoke them to add to other non smoked meals.
It seems to stand out nicely,without overwhelming.
Hope this helps a little.
