Query: Not for dummies

This book covers the way pressure cookers work, but he does not cover the electric pressure cookers which have been around long enough to have been included in his book. I did not feel the recipes were simple enough to be included in a Dummies book. Several were quite difficult to prepare. In the end, it seemed to be more of a cookbook with lots of recipes rather than a how-to-do-it book.
