I assume you are aware that the smokering is actually a nitrate/nitrite reaction in the meat.
I would suggest that you go to search at the top of the page,but I got hundreds of posts.
There are a couple of approaches.
You could add a couple pieces of charcoal to your woodbox.
You could leave some partially burned wood[charcoal]from the last cook.
You could actually begin to cure the meat ,by coating it with TenderQuick for a few moments and then rinsing it well.
Some folks do this on large cuts of meat,i.e. briskets,butts,large roasts.
Ribs would be iffy,as the small meat to bone ratio.
A forum member,Joe Ames,is a good place to ask about this and order ingredients.
Joe Ames Caution should be exercised,as you could wind up cured-like pink ham.
Hope this helps a little.
