Curious Cook in the New York Times: The red-meat miracle and other tales from the butcher case

My column in today's New York Times food section is about the redness of red meats and how it's maintained in both fresh and cured cuts. Check back for some other interesting findings about meat pigments and nitrites.


Note added on April 18: the column contains an error. In the sentence

Nitrite reacts in the meat tissue to form nitrous oxide, which bonds firmly to the iron in myoglobin and stabilizes it.

"nitrous oxide" should be "nitric oxide."
Nitrous oxide, also known as laughing gas, is N2O, and nitric oxide is NO.

My thanks to Professor Douglas T. Hess of the Duke University Medical Center for pointing this out--just hours after publication!
