First section of book is guide to living dairy free with advice and alternative dairy product ideas. It is aimed at wide range of people from vegan to dairy allergy (which is me) so good selection of information for all.
Second section is wide range of recipes from creating your own alternatives to dairy products to meals and cakes etc without usual dairy ingredients. I have tried soya cheese and really dislike it, so the wide range of dairy free "cheeses" appeal to me greatly. I am impressed with the range of recipes and the ingredients are not usually hard to obtain for them. In particular, there is an interesting looking "cheese" sauce recipe which I shall be trying once my secret ingredient (ok, it's just nutritional yeast) arrives in the post. There is also an index that cross references each recipe to various allergies, eg if egg or nut free, which is useful.
As another review pointed out, the book is aimed at the American market. For example particular dairy free brands available in America are recommended but with google UK alternatives can easily be found. However, as there is no such book for the UK market this is certainly not a problem for me. This book is definitely my dairy free bible!
