The Amazon fairy just deposited a copy of Ovenly (by Agatha Kulaga and Erin Patinkin) in my mailbox. In the front matter, it says:
As we sent out our recipes fo testing, we heard from friends, colleagues and family that none of them used the weight measurements we had provided. So, we decided not to use them in our book unless we felt it was necessary for a recipe. […]
However, if you are a person who prefers weights, we’ve created this handy conversion chart for you:
What follows are not conversion charts they have created, but the standard US customary–metric–Imperial conversion charts that are copy-and-pasted into every cookbook ever published. They are utterly useless for “[people] who prefer weights” because they don’t tell you how much the authors think a “cup” of flour (or indeed any other ingredient) weighs. Without having looked at a single recipe, this made me want to slam the book against the nearest wall. Whoever the idiot was who edited this book should not have let that one slip through. If you can’t be bothered to include ingredient weights, that’s fine. (Well, actually, it’s not fine, and I’m not going to trust anything else you have to say about baking, but I might still enjoy your cookbook.) But if you actually had ingredient masses already figured, took them out, and left in their place a worthless US-to-metric conversion table, that’s a special grade of stupidity.
