I have a sib who was an extremely fussy eater when she was a child. But one thing she loved was beef tongue with horseradish gravy. Mom would slow cook it in water, take it out and let it cool, then peel the outer skin and slice. When she was through, unless you knew enough about organ meats, you probably wouldn't recognize it. Meanwhile she'd use the cooking water to make a horseradish gravy.
One time sis wanted a friend of hers to spend the night (they were, I think, 13-ish). Mom said, I don't think so, we're having tongue or dinner tonight (this is way in the days before parents catered to everyone at the table's whims). OK, Just don't tell her. Her friend just lapped the whole meat up. Then sis, rather meanly, told her what is was. She ran from the room, horrified.
