In the 14th century Guillaume Tirel, a court chef known as "Taillevent", wrote Le Viandier, one of the earliest recipe collections of medieval France. During that time, French cuisine was heavily influenced by Italian cuisine. In the 17th century, chefs François Pierre La Varenne and Marie-Antoine Carême spearheaded movements that shifted French cooking away from its foreign influences and developed France's own indigenous style. Cheese and wine are a major part of the cuisine. They play different roles regionally and nationally, with many variations and appellation d'origine contrôlée (AOC) (regulated appellation) laws.
