First off, it has always baffled me how Red Cake has always been called 5100, and never did I hear it referred to as "just" a blender. It always had it's own unadulterated jar at The Briary and many other B&Ms, and in the Virginia threads it was always the favorite straight Virginia by a large faction, except for by the flake purists. Sure, many blends used it as a base or a blender, but that doesn't mean that most of us Virginia smokers didn't hold Red Cake dear to our hearts.
I would comment on the Sutliff vinegar aromatics, but I have resolved that if I can't find something nice to say about it... I'll keep making up jokes.
But, I am also not going to talk people into liking something that can't even be found any more. I am set for a long time with Red Cake in the cellar. Trying to talk it up, would be to foster jealousy and feed the tobacco scalpers. There is a world of wonderful tobaccos out there. Surely there is something else you might enjoy.
