pickled tongue - kosher only
On a similar note, my kosher butcher (Kosher Experience, ShopRite, Cherry Hill NJ) always seems to have only cured whole tongue, not raw for cooking. (I assume cured is like pickled.) The one time I asked if they had any raw, he was surprised and maybe a little impressed to be asked. Of course, he also gave me the spiel about how high in cholesterol it is.
