French cuisine was codified in the 20th century by Georges Auguste Escoffier to become the modern version of haute cuisine. Escoffier's major work, however, left out much of the regional character to be found in the provinces of France. Gastro-tourism and the Guide Michelin helped to bring people to the countryside during the 20th century and beyond, to sample this rich bourgeois and peasant cuisine of France. Basque cuisine has also been a great influence over the cuisine in the southwest of France.

Ingredients and dishes vary by region. There are many significant regional dishes that have become both national and regional. Many dishes that were once regional, however, have proliferated in different variations across the country in the present day. Cheese and wine are also a major part of the cuisine, playing different roles both regionally and nationally with their many variations and Appellation d'origine contrôlée (AOC) (regulated appellation) laws.

National cuisine

French cuisine has evolved extensively over the centuries. Starting in the Middle Ages, a unique and creative national cuisine began forming. Various social movements, political movements, and the work of great chefs came together to create this movement. Through the years the styles of French cuisine have been given different names, and have been codified by various master-chefs. During their lifetimes these chefs have been held in high regard for their contributions to the culture of the country. The national cuisine developed primarily in the city of Paris with the chefs to French royalty, but eventually it spread throughout the country and was even exported overseas.

Middle Ages

The ingredients of the time varied greatly according to the seasons and the church calendar, and many items were preserved with salt, spices, honey, and other preservatives. Late spring, summer, and fall afforded abundance, while winter meals were more sparse. Livestock was slaughtered at the beginning of winter. Beef was often salted, while pork was salted and smoked. Bacon and sausages would be smoked in the chimney, while the tongue and hams were brined and dried. Cucumbers would be brined as well, while greens would be packed in jars with salt. Fruits, nuts and root vegetables would be boiled in honey for preservation. Whale, dolphin and porpoise were considered to be fish, so during Lent the salted meats of these sea mammals were eaten.

Artificial freshwater ponds (often called stews) held carp, pike, tench, bream, eel, and other fish. Poultry was kept in special yards, with pigeon and squab being reserved for the elite. Game was highly prized, but relatively rare, and included venison, wild boar, hare, rabbit, and birds. Kitchen gardens provided herbs including some such as tansy, rue, pennyroyal, and hyssop which are rarely used today. Spices were treasured and very expensive at that time — they included pepper, cinnamon, cloves, nutmeg, and mace. Some spices used then, but no longer today in French cuisine are cubebs, long pepper (both from vines similar to black pepper), grains of paradise, and galengale. Sweet-sour flavors were commonly added to dishes by the use of vinegars and verjus combined with sugar (for the affluent) or honey. A very common form of food preparation was to finely cook, pound and strain mixtures into fine pastes and mushes, something believed to be highly beneficial to the ability to make use of nutrients.
