I agree with the other review written by the UK-based reviewer. I bought this book while home for a visit to America, not long after I'd developed a wheat allergy, and when I returned home the UK began trying to find some of the ingredients...at first I thought it was just a matter of figuring out the British names for some of these things (ie "garbanzo bean" being the same thing as "chickpea," which also is known as "gram flour" in the UK (& bears no relation to what is called "gram flour" in the US)). Unfortunately, however, there was a lot more to it than that. One of the main flours she relies upon is this garfava flour, and even trying to create your own version of it seems impossible, as fava bean flour doesn't seem to be available in the UK, even from on-line sources. Also, if you're vegetarian and/or have a dairy allergy (I'm both of these, as well as allergic to soy), this isn't the book for you: she uses a lot of milk powder, gelatine, etc, which I can't/won't use, and for which there aren't really equivalents in the UK which mimic closely enough the American forms of gelatine or dried milk...
Too bad, as otherwise it seems like a lovely book with some wonderful recipes! Will just have to pass it on to friends in the US whose twins are celiac...maybe they'll be able to use it.
