You just purchased a new cookbook and can hardly control the excitement of trying some of those new recipes. Your excitement turns to disappointment and frustration when some of the recipes just don't seem to work.
It may help you to understand that many cookbooks, especially first editions, contain a lot of errors.
I recently collaborated with a group of others on a new cookbook. All recipes were tested and the book was submitted for edit and publishing. When the book, with over 250 beautifully illustrated pages hit the stand it contained nearly five dozen errors involving about fifty of the recipes.
As you might expect, errata information was made available. Nevertheless, I'm certain there were a lot of disappointed people who worked carefully with the instruction first provided.
Moral: The moral here is two fold - 1. Learn as much about cooking and how ingredients relate to one another so that you recognize when something doesn't look quite right in a recipe. 2. If a new recipe doesn't turn out as you had expected it may not be your failure.
