"but stubbs burned solid right through"
Stubb's is solid all the way around....yes a tad smokey at the start, but unmatched for long burn cooks like pork butt.......NEVER fails to chain..........
PS: Here's an almost finished chain....notice right by the shadow on the left is an unburnt Kingsford....
This chain........
Which was lit with Stubb's...which caught quickly, very quickly & without fuss.....
Only reason I did the chain in Kingsford's was it was already set up to show a buddy how to do it.....his is running today I think.....
Use Stubb's any chance you get.....the food will just come out better all around.....
