Here’s a minor but slightly interesting take from one of the more well-known grilling/smoking gurus on the internet:
The guy from Ballistic BBQ says (on his PBC brisket video) that the PBC is the only smoker he uses wood chips in because it’s so efficient. (Now, it’s possible he’s just a shill for PBC, but I have no reason to doubt his sincerity on this.)
I’ve receive plenty of wood chips as gifts from well-meaning folks and they’ve just sat in my garage for years, but I’ve started using them from time to time on the PBC and I get good results. I think chunks are still the way to go if you’re going to add wood, but chips really seem to be a decent option if you already have them.
At least I have a viable use for mine now.
