I would divide this book in to two sections: tea context (including some historical notes, tea taxonomy, and enjoyment guide) and recipes.
I read the abridged version of this book (The Tea Deck) as an ebook recently and a friend happened to have the fullsize paperback, so I borrowed it to compare notes. The text was mostly the same, minus a few quips and stories and minus a few recipes. As an aside, I prefer baking recipes that are written by weight, as opposed to as this book has them by volume. The results are always easier to control.
To be frank, I've read several better tea history books, better tea enjoyment guides, and better tea taxonomy texts. This book does not really shine in these areas. Some of the recipes are interesting, though only a few of them involved using tea itself, which was my complaint about the abridged guide.
One note about this edition is that the photographs are MUCH nicer than The Tea Deck that I read. The colors and quality of loose tea are much closer to as they should be presented.
