Actually Dulcis is a good decription, Dulcis is latin for sweet.
From my understanding (which my understanding has been known to be VERY flawed) in some parts of latin america there was a desert treat made with caramel and vanila.
Basicall, what you are looking for is a caramel tobaco or an RY4 (now that is as undescriptive name as can be).
As a note, RY4s can vary greatly between vendors. A simple caramel tobaco is more like to find a close match.
