What would you find in the middle of a Baked Alaska?

No, this igloo-shaped dessert — cake, and ice cream shrouded in toasted meringue — didn't come from the icy north, but its name was inspired by the land deal. The treat's true roots date back to the turn of the 18th century when American-born scientist Sir Benjamin Thompson (aka Count Rumford, a title he gained for his loyalty to the crown during the American Revolution) — whose inventions included a kitchen range and a double boiler — discovered something about egg whites. Rumford realized that the air bubbles inside whipped egg whites made Meringue a great insulator. "That's really why Baked Alaska works," says Libby "O'Connell, the History Channel's chief historian and author of The American Plate. "The meringue insulates the ice cream from heat."
