Three days later the congress was drawing to a close, and over 50 chefs from all over the world had taken their turn onstage. I couldn't help but feel a bit empty. Where were the culinary fireworks? The introduction to the next ingredient that was going to enable us to turn oil into powder, serve a gelled liquid hot, or thicken an infusion by simply blending in a magical white substance? Where were the explanations of new techniques? Like the ones used to create raviolis with skins made from themselves, making pasta from stock, and aerating food to produce sponge-like textures? Surely someone was ready with the next method of changing texture and form, like the liquid nitrogen that became popular in the professional kitchen five years ago? Where were the equivalents to the freeze-drying machines? Centrifuges? Rotary evaporators? Vacuum sealers?
