When I did my ribs smoke at 235 deg F, I used one Smokin-It hickory block that was about 1-1/2 inches thick. After 1-1/2 hour smoke, only thing left was about a 1/2 inch square ember.
On the prime rib smoke, I used two pieces of wood. The Smokin-It hickory block was 1-1/2 inches thick, the Smokinlicious block 1-1/4 inch thick. Both just charred the surface a bit, at 200 deg F for six hours.
Guess I would have thought that if 1/2 inch thick pieces were required, Smokin-It would have instructed us to chop up the wood blocks they sent. Or they would have just cut them the correct size before shipping.
My friend with the Cookshack Amerique uses the Smokinlicious standard wood chunks as-is, and always gets wood burn to ash. This is supposed to be a higher temp element. Am wondering if I still have an issue with element temp.
