Question: how long does it take to cook a 3 1/2 pound brisket?
Answer: Sear brisket directly over medium coals or near a hot fire: 20 minutes per side. After searing, allow approximately 1 hour of cooking time per pound. Slow cook at a low temperature of 250 ˚F. Measure cooking temperatures in a closed pit or grill with an oven thermometer set near the brisket.
