I bought a smoker box for my gas grill as i found several recipes that i wanted to try that called for it. Recipe said to soak the wood chips for at least 30 minutes before placing in the box and on the grill. So here's my stupid question - the chips are not going to smoke until they dry out so why do I need to soak them for 30 minutes? Why not just put them in the box dry and save myself 30 minutes worth of propane? Am I missing something?
