The book is visually great, and has many helpful tips and instructions, particularly the paragraph with every recipe that explains what the testers did and why they did i, and why some things don't work.
Unfortunately, like most slow cooker books, the quantities are for larger numbers of people. I emailed the Test Kitchen and was told that I should feel free to experiment, but that they could not guarantee the results. This is great for a test kitchen, but not so much for dinner every night!!
