The Split Decision pie-pan lets you bake two pies in the same receptacle, settling any arguments about which sort of pie should be had that day and generating handsome, smooth half-pies the like of which humanity was not meant to ken of.
I'm not enough of a baker to know if different sorts of pies have different cooking times/temperatures, but I'm assuming that they'll all be within a certain range that is determined by the need to cook (but not burn) the crust.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
