Pork Butt

Pork butt is fairly straightforward to cook except for the cooking time.  If you read the post on brisket you will understand "the stall."  This is a period of time when either evaporation or rendering of fat causes the temperature to hold still rather than raise.  This stall seems to completely depend on fat content.  Therefore, as with brisket, you should make sure that you add an extra 4-5 hours to your estimated cook time to account for the stall.
