Elizebeth designed a menu that listed one of the courses as “An Indecipherable Cipher.” A guest wondered if this meant “hash,” a cryptographic term for a string of text that gets scrambled once and never unscrambled, like a door that locks forever behind you (today hashes are used to protect Internet passwords). The guest was delighted when Elizebeth arrived from the kitchen carrying a steaming plate of meat-and-potato hash.
