As barbecue purists will tell you, it’s hard—if not impossible—to produce the same quality of smoke on a gas grill as you can over charcoal. That said, a gas grill is infinitely more convenient. There’s no messy setup or cleanup: Just flip a switch and you’re good to go. For this recipe, we challenged the assumption that a gas grill is an inferior choice for smoking meat and nailed down an ironclad method that eliminated inconsistencies when smoking over gas, delivering pulled pork that rivaled that made with a charcoal grill.
