In this semi-final, the last three contestants face off in a brand-new format: each challenges their opponents by setting them a culinary task of their own choosing. The three challenges: First challenge: to make a tricolour ravioli without artificial colourings. Second challenge: to cook snails without cargolade or maître d’hôtel butter. Third challenge: prepare a boneless stuffed poultry dish, without sauce. Following these three technical challenges, the five judges, joined by guest chefs Pascal Barbot, Pierre Gagnaire and Guy Krenzer, will decide between the contestants to select the two finalists who will compete in the Top Chef grand final.
