One of my great working books has two weaknesses : it has no workable index, and it is extremely big (about 900 pages).
So this is one of the cases where Bless EYB :) :)
However, for this book, all the page numbers are missing. That means I have to go through the one or several most meaningful 7 sections of my 900 pages books to find the appropriate recipe. What does not help is also that a lot of the recipe have the same name (this is an encyclopedia of Italian cooking and you have several variations of the same recipe), so it means I also have to cross check the ingredients with the site to check whether it is the right recipe.
Slightly unnerving.
