In the second episode of Bravo's "Top Chef," the kitchen heats up as the contestants are challenged to cook up sweet dishes that are both sexy and erotic, under the watchful eye of guest judges Elizabeth Falkner, owner of Citizen Cake, a celebrated patisserie and dessert hotspot in San Francisco, and Mistress S, who runs a fetish ball and knows a thing or two about eroticism. The two judges join Katie, Tom and Gail to help decide which scrumptious creations have made the cut and which one will send another chef packing their knives for home.
