Today I happened upon this article about Hormel on Mother Jones. It is a long but worthwhile read, infuriatingly disturbing on many levels, and highly condemnatory of industrially produced food products.
But that is not why I am posting.
Early in the article, it mentions that the offending liquified pig brains are used as such:
"When the 10-pound barrel was filled, another worker would come to take the brains for shipping to Asia, where they are used as a thickener in stir-fry. "
The hyperlink on 'thickener in stir-fry' just leads to an article affirming that it is safe to eat fully cooked pig brains.
I have heard of corn, potato, and lotus root starch as thickeners in stir fry. Never pigs brains. Asia is a big place...does anyone know which country is likely to be buying this industrial pig brain waste and having it shipped in for use in stir fries? How is it used as a thickener?
