content: I purchased this book with my new pressure cooker. It has some wonderful tips. It gives you an idea of how long to cook beans, soups etc... also shows you how to use your own recipes with a pressure cooker. The practical workings of a pressure cooker are explained to you and that was very helpful as I had never used one before. My experience has been that not all the timings are correct, at least for my altitude. For example if I cook the beans as long as the book says my beans are mushy. But it was a good start and I've learned how to adjust the timing. Over all the book was very helpful.
