Title: Temperature and cooking duration
Review: The book is excellent from the point of view of explaining ingredients. However, I think they really blew it in the sense that they do not provide any information whatsoever with respect to various oven heat choices...convection, surround, top, bottom etc. The result is that unless you are an experienced cook, you still are faced with a lot of experimentation to get a reliable satisfactory baking outcome. Just think how helpful it would have been to have an matrix of oven setting choices and cooking duration accompanying each recipe.
