Fried chicken. Waffles. New York. Los Angeles. The Southeast, and (a little bit of) Pennsylvania Dutch country. Erin and Katherine explore the histories of waffles and fried chicken separately, then talk about how they came together -- and Katherine tries to keep her angry ranting about Thomas Jefferson to a minimum.

Cioppino is San Francisco's unofficial official dish, invented during The City's bohemian, Barbary Coast heyday. (More 1850s than 1970s). Katherine and Erin talk about the red-wine-and-shellfish stew's Italian-ish origins, hairy-chested poet-fishermen, and what really goes on in the Bohemian Club. (Katherine knows. Her Grandpa's in it.)

Katherine and Erin talk about cheesecake, the all-American (by way of ancient Greece)dessert that has become practically a standalone industry. There is some talk of placenta (sorry! But it is related!), but then we share an ancient cheesecake recipe, talk about innovative dairy farmers, and compare New York, Italian, and Hungarian cheesecakes. Plus there's an Anthony Bourdain spotting.

Katherine figures out who exactly invented the cheeseburger -- it's not the person who got the trademark! She also scoffs at the long-held belief that Mongol hordes tenderized meat under their saddles. Erin lays out the best cheeseburgers in existence right now, and tells us about partying at the Playboy Mansion.
