Lump charcoal and hickory chunks. I almost ran out; the store where I usually buy charcoal only had briquets last week, which is why I bought the hickory chunks.

I welded up a charcoal basket out of perforated steel that fits my side fire box really well and I think this saved a lot of fuel for me. I probably used half as much as I would have without the basket. I'm going to build another basket so when it's time to add fuel I can just swap in a whole basket full of fuel already burning. I used the minion method (layers of charcoal and hickory in the basket) which seemed to work well.
