In an article in the March 22, 2006 Chicago Tribune is the news that a 75th anniversary edition of The Joy of Cooking will be published by Charles Scribner's Sons in November 2006. The editors have chosen not to "dumb down" the instructions but will be including a glossary of cooking terms for those who do not comprehend "blanch," "braise," "cream," "fold," and "saute." Some recent cookbooks and cooking magazines have removed these words because today's cooks do not understand them.
A lengthy account of the country's culinary vocabulary deficit can be found in "Boiling It Down for Cooking-Challenged" by Candy Sagan in the Chicago Tribune, March 22, 2006, Section 1, page 10. The same article was in the Washington Post on March 18 as "Cooking 101: Add 1 Cup of Simplicity."
Neither Baker & Taylor nor Amazon yet have information on the new edition of The Joy of Cooking. The website for Sharles Scribner's Sons also has no information that I can find.
