I brought back a couple of these from Mitsuwa in NJ only to find that one of them was almost completely rotten! I'd like to replace it. Has anyone seen these around here? I've never looked, so for all I know, they could be right under my nose. The closer to Porter Sq the better. Thanks!
Btw, a rotten purple sweet potato smells strongly of umeshu/Japanese plum wine. If it weren't for the brown color or crumbly texture, I'd guess it might taste pretty good!
