The product states that 6 or 7 should be used but I would assume that recommendation would be for a 22 inch kettle, so for the first time using this product I used 2 with the SJ. Maybe I would try 3 the next time. I guess it depends on how much smoke you want. To clarify my post, these briquets did not ignite into flame the way wood chips often do and leave a burnt taste. For the SJ two of these worked okay with a steak. If I was not pleased I would not post. For myself, I do not try to achieve heavy smoke taste.
