This is a beautiful book indeed. One must overlook the English translation's error inside, wherein the word 'macaron' is spelt with an extra 'o', unlike its cover.
However, this is not an impractical book as some reviewers suggest. It is very easy to use and understand; I say this having made the salted caramel macarons successfully on my very first attempt (ever) at macarons. I am now making the coffee and blueberry ones, and as long as I keep up my vigilance, I expect them to be as successful as my first three batches of macarons.
Believe in yourself, and give this book --or simply making macarons-- a try. :)
