Lincoln biscuits remind me of my Nana Pidge, my dad's mother, partly because she would serve them but chiefly because in a drawer in her kitchen there was a trick one. It looked like a Lincoln biscuit from one side but then you turned it over and there was a mirror on the other side. I don't think I ever genuinely caught anyone out with it but the very idea thrilled me.
