In this week's live chat, a participant who calls herself "popovergirl" (a woman after my own heart) chimed in during a thread on the late, great Ediner.

"I have a recipe for Ediner brownies somewhere...." she wrote. Later that day, she generously forwarded it in an email.

"I don't think I've ever made them, but my friend Beth has," she wrote. "[It's] from a weird charity cookbook she had called 'Food for Show, Food on the Go!'"

Then she added a link; she had discovered a copy of the book for sale on Amazon.

Anyway, I baked them this morning. They're pretty swell. Not that I'm surprised, because in its heyday, the Ediner really had it going on.

The restaurant -- a retro-bathed tribute to short-order cooking, done up to resemble a railroad dining car and originally located in the Galleria -- was founded in 1982 by Susan and Jack Seltz. The concept (a diner, in Edina; get it?) quickly blossomed into a mini-chain with six locations, with additional outlets in Roseville, Minnetonka, Uptown Minneapolis, Detroit and Toronto.

Unfortunately, the growth was short-lived (after the Seltzes sold the company, it went through three different ownerships), and when the Calhoun Square location sputtered to a close in 1992, only the original Ediner in the Galleria remained standing; it shut down in 1995. But it was fun while it lasted, right? (The Galleria location has been home to Big Bowl for nearly 15 years, and the Calhoun Square location is now the site of Republic).

As for the recipe, it's one of many bonuses found inside our live chats. We conduct them on Thursdays from noon to 1 p.m. (the next one is Feb. 21st). Find them at startribune.com/taste, and the transcripts are archived here.
