When Matali Crasset whips up lighting for an Alessi Takes The Cake event in New York this weekend, she uses the supplies at hand: about 280 whisks for two large lamps. The installation has been designed to celebrate the Italian company's "Essentiel de Pâtisserie" collection, a collaboration between renowned designer Matali Crasset, and famed French pastry chef, Pierre Hermé.
