What would they use in the hot dog if it's not lips and assholes?
You should try to sneak your own through the gate. You could stash it in the front. They won't check hopefully.
I've ran it around 300 and found the meat had more of a roast beef type of flavor.
Found below 275 it has the "brisket" flavor I'm looking for. Both are still pretty darn good though.
