If you look back to this thread you'll see one concern that comes up pretty quickly--translating Euro and American measures.

I would suggest, if someone doesn't want to make the calculations for such a book (and check them twice!) that a very good conversion chart be included at the front of the book, and a column should be left open (perhaps with an _____ before each line, like



_____ 1 cup whole wheat flour

_____ 1/2 cup shortening

So that the cook can either go with the quantities as printed or use the conversion chart and write in their preferred measure.
