At the time that I purchased my Ultramel from Eric Crider over a year ago, he had not yet determined if the Ultramels were the same (and therefore compatible with) the Crider Caramels which bear his name. Criders are different from the standard caramels (and not compatible). Ultramels were more recently brought in from Africa and the last I'd heard is that compatibility with the Criders had not yet been determined. I've seen similarly aged Ultramels and Caramels side by side and they are clearly different. I have not seen a Crider in person, however, so I cannot speak on how they compared with Ultramels and Caramels in appearance.
