I have heard people mean brains by using the term “sweetbreads” but, that is not a correct usage. Sweetbreads are generally thalmus glands though some do like to use pancreas.
in OH there is a diner that serves fried cow brains ...sweetbreads... per my last scientific evaluation of the topic ~2006
Any idea if they ever are made with brains?? I had a chef at a high end resort tell me they were brains after he had me try them.... LOL. I always thought I had tried brains after that.
