The city’s top dessert chefs, from Johnny Iuzzini on down, delighted deep-pocketed foodies with their signature confections at Sweet on Friday night. Evian and Ferro Rocher flexed their marketing muscle, dispatching well-formed young people in tight clothes to represent their not especially sexy brands. The pastry aristocracy (Goldfarb, Iuzzini, and Stupak) were all present and accounted for, standing proudly behind space-age-looking creations that tasted even better than they looked. (Only Sam Mason wasn’t around, as someone had to man the stoves at Tailor.) At first we were sort of alarmed: There were obviously many more guests than had originally been intended, for the long, narrow, space, but since cake isn’t combustible, it all seemed safe enough. A body can only take so much chocolate ganache, Champagne, and high-powered pastry cooks crammed into one hall.
