The day before grilling: Wash the beef brisket, pat dry, mix spices for the dry rub, lightly coat with rapeseed oil, massage the rub over all surfaces, wrap tightly in cling film, and refrigerate overnight in a bowl. Reserve any remaining spices.
The next day, prepare the grill with a full gas bottle (have a spare if possible).
Place the brisket in an aluminum dish on the grill, using indirect heat (for a three-burner grill, position the dish in the middle and turn on the two outer burners to low). Close the lid and cook for 60 minutes, monitoring the grill chamber temperature with a thermometer (not the lid thermometer, which is often inaccurate).
After 60 minutes, add a batch of soaked smoking chips (either wrapped in foil or in a smoke box). Close the lid and let the smoke develop.
Mix the remaining spices with apple juice and whiskey in a bowl.
Use a silicone brush to baste the meat repeatedly with the spice-juice mixture. Continue basting and add more soaked smoking chips every hour or more often for greater smoke flavor.
Place a second thermometer probe in the center of the meat. Cook for approximately 9 hours at 110°C (230°F), reducing to 90°C (194°F) toward the end if needed. Target core temperature is 83–92°C (181–198°F).
Remove the brisket from the grill, wrap in aluminum foil, and rest for 30–60 minutes in a cooler or at 65°C (150°F) in an oven.
Slice the meat against the grain.
Do not increase the grill temperature if the core temperature is rising slowly. High heat will dry and toughen the meat. It is better to allow extra cooking time than to risk ruining the brisket.
Each piece of beef varies naturally. Be prepared to adjust temperature and cooking time as needed during the process. Purchase well-aged brisket from a butcher and order large cuts in advance.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
