Last week, Syfy offered Grub Street readers the chance to win a copy of Nathan Myhrvold's megaepic Modernist Cuisine. (The book was recently named Time's 64th "most influential thing in the world," which as Francis Lam points out is only twelve spots behind jeggings!) All you have to do is leave a comment on this post right over here, giving us an idea for a Marcel's Quantum Kitchen episode theme and a corresponding dish that Marcel Vigneron could make on it. Easy! We're picking our favorite at noon eastern tomorrow, so head on over and enter while you still can!
