Sorry about the basic question but here it goes. I just purchased my WSM 18.5 last weekend from Lowes. I also purchased a bag of Cherry and a bag of Apple wood chips. They did not seem to have wood pieces. As I look at the various recipes most seem to use wood pieces not chips. If a recipe says to use 3 pieces 2 X 2 X 3 is there a rough equivalent amount for chips? Also it seems to me that the chips are more apt to burn up quicker. Are they to be soaked and then placed directly on the coals or should they be wrapped in foil in order to slow down their burn rate? BTW my first cook was a whole chicken with a basic rub. About 4 hours at 240. I water soaked a handful of Cherry chips for an hour and then placed them directly on the hot coals. I also added the water I soaked the chips in to the water in the water bowl. I had lots of smoke for the first hour then it tapered back. The chicken turned out great, nice crispy skin and tender and moist inside - I must have got lucky. Any advice about the chips would be appreciated. Thanks - James.
