I am not really exactly buying into the full premise of this article. While to a large degree the lack of exposure of this branch of japanese cuisine is based on bias... It also is clearly based on the fact that these are the least desirable cuts of flesh and offal from the least desirable livestock animals.<p>Much like sure you CAN really masterfully make something chittlins taste as good as intestines can taste... its still going to be viewed as lower class leftover scraps because thats really fundamentally what it is at its core.
