Interesting conversation on WSM water pans. Many great points of view from longtime kettleHeads right down to first time posters (by the way, I'm I allowed to use BTW,
@rjmitch89, hello and welcome to the discussions here on the WKC from Eugene, Oregon).
Let's keep this going, shall we??? Why use a water pan at all on a WSM??? 'Cause it was part of the original product purchase??? Well, maybe the question is why use water in a kettle or smoker??? After all, most of use know that a "damper" on our beloved WSM is a boon to the final result and does not need to have any water involved. (Here damper means: foil wrapped water pan, or foil wrapped clay pot liner, or
)
Here is my current thinking:
(1) Mostly to control temp's??? I dunno, my WSM 18", w/o water, holds temps to + or - 10 degrees. When you're new to kettling (is that a word), that sounds WAY our of bounds, but as you progress you realize that meat cooks just fine at + or - 20 degrees of these magic numbers. Soooooo, why so much concern over tight temp ranges???
(2) Water moisture in the cooker aides in "smoke ring creation" according to many including Raichlen, but I don't cook my meat so that someone else thinks that I have a huge "smoke ring" for what ever that's worth.
(3) Well I'm not aware of a "real" third reason, but com'on cookers, help me learn a little more of the value of water in the water pan.
