according to ratio of ingredients; I mean, I heard traditional French
meal always contain a reasonable piece of protein (either fish,
poultry or red meat), as well as _moderate_ amount of carbohydrates,
and never excessive amount of fat.

It's been cited to me such dishes are usually prepared in 4 stars
restaurants. And I know it is true, I like French cuisine, i.e.
restaurants.
Please tell the title of a French cookbook where such dishes at least
dominate (seafood is preferred food, but it's not as critical).

Or please tell, if it's any easier... from what part of France I
should search for a such a cookbook, Alsace, Provence, Burgundy,
Britanny... ?

Thank you very much.
