Well I picked up some of that ONO charcoal at the local BBQ Galore and decided to give it a whirl and T-Rex some rib steaks.
I am sure that the Whiz will shortly do a review (searched and didn't find any), but my impressions were that the pieces I got were quite large, no mill scrap, it got hot, not much of a strong odor, but it did seem to ash more than oak.
Anyway, I was in the middle of the sear phase and I hear this loud "POP" and the grate "jumped" a bit. Turns out I cracked the outer edge and one of the inner ribs of my cast iron grate!
Anyone else have this problem?
