I just found the following instructions written by a reader of "Inglenook Magazine" and included in the Inglenook Cook Book:
"Take 8 tablespoonfuls of flour, enough water to dampen the flour; rivel with the hands and put the rivels into fresh beef broth"
I certainly had never heard the word "rivel" before.
I also found some fun contextual instructions in the same book:
"After church, visit or washing (according to the day) add to your beans a teacupful of sweet cream; salt to taste, and serve."
What interesting instructions have you run into?
