Finally getting around to posting these. Did these short ribs on gasser (still my only way to grill for me unfortunately), 250-275 for 5 hours. Smoker box help hickory chunks. Fat didn't melt out as much as I'd like. Next time I'll go 225 for longer.
Rubbed with salt, garlic powder, GrillMates BBQ rub, and heavy pepper.
Added Rays to 2 ribs at the end. 2 left dry at my wife's request.
Thanks for looking
