So i am smoking a brisket for passover tomorrow and want to make an au jus to go with it. I am using chef jimmy j's recipie but have a question. After i add the beef broth how long should i smoke it for? I am thinking leaving it in for the duration of the brisket smokr would be a bit too much. I am thinking more that it should be like 5 or 6 hours? Any input on how long to smoke the au jus after adding the broth would be much appreciated!
