Fascinated by cheesesteaks, all the lore and more?

Then check out The Great Philly Cheesesteak Book, new from Philadelphia's Running Press.

Author Carolyn Wyman (Spam: A Biography) doesn't fret about ratings and reviews as much as she dishes out heaping portions of local color, history and helpful info, like recipes. (Cheesesteak pierogis? Italian rolls!)

Want to know who serves what meat on which rolls? She tells you for 38 major steak shops, from Pat's and Geno's to Claymont Steak Shop in Delaware - and shares stories about the folks behind the food.

Want a fix while out of town? Consult the "Shore Tour," or a list of cheesesteak places around the country, or the rundown of who'll ship cheesesteaks - at tough-to-digest prices.

The book even includes a DVD of the "only" cheesesteak documentary, This Is My Cheesesteak, by a former vegetarian who made one yearly exception: "to have one real cheesesteak - after which I got sick."

Surprisingly, there was a book on Scrapple, but not one about cheesesteaks, said Wyman, 53, who will lead a bike ride tomorrow to eight city steak shops.

In the spirit of this browseable book - actually, culled from its very pages - we offer up this list of ...

25 Things Betcha Didn't Know About Cheesesteaks

1. Even when Tony Lucidiono Jr., owner of Tony Luke's, weighed 325, his cholesterol didn't top 165. He credits cheesesteaks.

9. The food-service grade Cheez Whiz used by restaurants has more real cheese than the jarred stuff sold at supermarkets.

13. To order a cheesesteak in Russian, say "Mne pozhaluista buterbrod so steikom, s lukom i syrom."

17. "In order to be cut to the traditional paper-thinness, the meat must be at least somewhat frozen."

18. The $100 Kobe Cheesesteak at Barclay Prime switched to adding sauteed lobster after animal-rights activists objected to the foie gras. Price includes champagne.

Wyman - who with her husband freely chose to move to Philly about seven years ago, partly for the food - said the book was a labor of love.

With most products, you run into lots of "corporate speak," she said.

Not with Philly cheesesteaks.

"It's real people with their own ideas about things," she said. That's what made the subject "refreshing and great."
