I am a bit wary of Amazon reviews so I am asking here, are these books useful today? useful here means; are there any objective scientific practices outlined in them that we accept today? They are not fraught with misinformation to the point where it becomes advisable to stay away from them?
(1)The Original Fannie Farmer 1896 Cook Book
(2)The Boston Cooking School Cook Book 1918
Is it better to get something derived from these books such as Fannie Farmer Baking Book 1996 by Marion Cunningham and The Fannie Farmer Cookbook Anniversary Edition September 9, 1996 by Marion Cunningham? The older books are cheaper.
