Query: Worst Book in my library

This is the worst book in my Library. It uses "Salt Peter" for curing, instead of the more modern Tender Quick or Cure #1. The recipes must be really old to use a cure that really isn't even sold to the public for curing meat any more.Save the money you'd waste on this book, and use it for shipping charges for a much better book. There are many!
