Ethnic and immigrant influence.

The demand for ethnic foods in the United States reflects the nation's changing diversity as well as its development over time. According to the National Restaurant Association,

Restaurant industry sales are expected to reach a record high of $476 billion in 2005, an increase of 4.9 percent over 2004... Driven by consumer demand, the ethnic food market reached record sales in 2002, and has emerged as the fastest growing category in the food and beverage product sector, according to USBX Advisory Services. Minorities in the U.S. spend a combined $142 billion on food and by 2010, America's ethnic population is expected to grow by 40 percent.

A movement began during the 1980s among popular leading chefs to reclaim America's ethnic foods within its regional traditions, where these trends originated. One of the earliest was Paul Prudhomme, who in 1984 began the introduction of his influential cookbook, Paul Prodhomme's Louisiana Kitchen, by describing the over 200 year history of Creole and Cajun cooking; he aims to "preserve and expand the Louisiana tradition." Prodhomme's success quickly inspired other chefs. Norman Van Aken embraced a Floridian type cuisine fused with many ethnic and globalized elements in his Feast of Sunlight cookbook in 1988. The movement finally gained fame around the world when California became swept up in the movement, then seemingly started to lead the trend itself, in, for example, the popular restaurant Chez Panisse in Berkeley. Examples of the Chez Panisse phenomenon, chefs who embraced a new globalized cuisine, were celebrity chefs like Jeremiah Tower and Wolfgang Puck, both former colleagues at the restaurant. Puck went on to describe his belief in contemporary, new style American cuisine in the introduction to The Wolfgang Puck Cookbook.

Another major breakthrough, whose originators were once thought to be crazy, is the mixing of ethnic cuisines. It is not at all uncommon to find raw fish listed next to tortillas on the same menu. Ethnic crossovers also occur when distinct elements meet in a single recipe. This country is, after all, a huge melting pot. Why should its cooking not illustrate the American transformation of diversity into unity?

Puck's former colleague, Jeremiah Tower became synonymous with California Cuisine and the overall American culinary revolution. Meanwhile, the restaurant that inspired both Puck and Tower became a distinguished establishment, popularizing its so called "mantra" in its book by Paul Bertolli and owner Alice Waters, Chez Panisse Cooking, in 1988. Published well after the restaurants' founding in 1971, this new cookbook from the restaurant seemed to perfect the idea and philosophy that had developed over the years. The book embraced America's natural bounty, specifically that of California, while containing recipes that reflected Bertoli and Waters' appreciation of both northern Italian and French style foods.

Early ethnic influences.

While the earliest cuisine of the United States was influenced by indigenous Native Americans, the cuisine of the thirteen colonies or the culture of the antebellum American South; the overall culture of the nation, its gastronomy and the growing culinary arts became ever more influenced by its changing ethnic mix and immigrant patterns from the 18th and 19th centuries unto the present. Some of the ethnic groups that continued to influence the cuisine were here in prior years; while others arrived more numerously during “The Great Transatlantic Migration (of 1870—1914) or other mass migrations.

Some of the ethnic influences could be found in the nation from after the American Civil War and into the History of United States continental expansion during most of the 19th century. Ethnic influences already in the nation at that time would include the following groups and their respective cuisines:

· Select nationalities of Europe and the respective developments from early modern European cuisine of the colonial age:

· British-Americans and on-going developments in New England cuisine, the national traditions founded in cuisine of the thirteen colonies and some aspects of other regional cuisine.

· Spanish Americans and early modern Spanish cuisine, as well as Basque-Americans and Basque cuisine.

· Early German-American or Pennsylvania Dutch and Pennsylvania Dutch cuisine

· French Americans and their "New World" regional identities such as:

· Acadian

· Cajun and Cajun cuisine

· Louisiana Creole and Louisiana Creole cuisine. Louisiana Creole (also called French Créole) refers to native born people of the New Orleans area who are descended from the Colonial French and/or Spanish settlers of Colonial French Louisiana, before it became part of the United States in 1803 with the Louisiana Purchase.

· The various ethnicities originating from early social factors of Race in the United States and the gastronomy and cuisines of the “New World,” Latin American cuisine and North American cuisine:

· Indigenous Native Americans in the United States and American Indian cuisine

· African-Americans and “Soul food.”

· Cuisine of Puerto Rico

· Mexican-Americans and Mexican-American cuisine; as well as related regional cuisines:

· Tex-Mex (regional Texas and Mexican fusion)

· Cal-Mex (regional California and Mexican fusion)

· Some aspects of “Southwestern cuisine.”

· Cuisine of New Mexico
