(I knew you'd look! Don't say I didn't warn you!)

There is a famous-in-certain-circles Kentucky folk singer named Jean Ritchie, and she wrote a book about her family life when she was a child. (Circa the 1930's.) In it, she mentions that when her father got to an age where he had lost a great many of his teeth, his diet consisted primarily of one food: peanut butter stirred together with honey. He called it 'gray horse'. Has anyone else ever heard of this mixture being called this?
