Kerry, what a great idea for a topic! It was fun, too, seeing the names and avatars of all those former, and wise, eG'ers, and wondering what they're up to nowadays.
What immediately came to mind wasn't a post or topic per se -- it was anything Paula Wolfert wrote.
As you might know, about three years ago Paula was diagnosed with Mild Cognitive Impairment, an early stage of the Alzheimer's form of dementia. Here's a 2013 article from the Washington Post about that. And here are last year's articles from Bon Appétit, The Wall Street Journal, and kitchn about the Kickstarter campaign for her biographical cookbook, now scheduled for publication next spring.
This is one of many favorite posts: stratification. I had been making sauces like this for some time without truly knowing exactly what I was doing, or why.
And this is a favorite topic: Cooking with "The Cooking of Southwest France". I'm proud to say I was one of those eG'ers who did recipe-testing for the 2nd edition of the book. I still have the email I sent back to her with my feedback, almost exactly twelve years ago.
