Start with Brad Makes an Outdoor Grill (Part 1) (22 min, Bon Appétit), then I Tried The #1 BBQ In Texas (38 min, Joshua Weissman). All 895 lessons here are free, from the teachers' own official uploads. You'll need instant-read thermometer, wireless meat thermometer, butcher paper roll and a few more basics (about $125 of kit). The book to keep beside you: Franklin Barbecue by Aaron Franklin.
