I am reviving this old thread as I stumbled across this great article on Smoke Rings and how to achieve them and why we don't get them in our electric smokers.

For what it's worth I smoked a Turkey Breast this weekend and added a Water Pan to the smoker. It did NOT give me even the slightest indication of a pink smoke ring. In fact I felt that it did make the breast taste more moist than without the water pan however I personally felt it tasted LESS smokey.

Verdict.....don't use a water pan in the smoker to try and achieve a smoke ring. My next experiment will be a couple charcoal briquettes.
