Lancelot de Casteau or de Chasteau or de Chestea, also known as Anseau de Chestea (died 1613) was the master chef for three prince-bishops of Liège in the 16th century: Robert de Berghes, Gérard de Groesbeek, and Ernest of Bavaria and the author of a cookbook, the Ouverture de cuisine, often considered the first cookbook to go beyond medieval recipes and to codify haute cuisine.
