Helge Rubinstein: The Chocolate Book, Penguin Books, 1982
This book has been on my bookshelves since publication, but unfortunately, as a paperback which was glued together, the pages are loose and it has to be used carefully. (My edition is OOP.) It is well-written and filled with fascinating information, as well as recipes and will be very useful in the weeks to come.
And did you know that Helge Rubinstein founded Ben’s Cookies?
