West African cuisine encompasses a diverse range of foods that are split between its 16 countries. In West Africa, many families grow and raise their own food, and within each there is a division of labor. Indigenous foods consist of a number of plant species and animals, and are important to those whose lifestyle depends on farming and hunting.
The history of West Africa also plays a large role in their cuisine and recipes, as interactions with different cultures (particularly the Arab world and later Europeans) over the centuries have introduced many ingredients that would go on to become key components of the various national cuisines today.
Centuries later, the Portuguese, French and British further influenced regional cuisines, but only to a limited extent. However, as far as it is known, it was European explorers and slaves ships who brought chili peppers and tomatoes from the New World, and both have become ubiquitous components of West African cuisines, along with peanuts, corn, cassava, and plantains. In turn, these slave ships carried African ingredients to the New World, including black-eyed peas and okra. Around the time of the colonial period, particularly during the Scramble for Africa, the European settlers defined colonial borders without regard to pre-existing borders, territories or cultural differences. This bisected tribes and created colonies with varying culinary styles. As a result, it is difficult to sharply define, for example, Senegalese cuisine. Although the European colonists brought many new ingredients to the African continent, they had relatively little impact on the way people cook in West Africa. Its strong culinary tradition lives on despite the influence of colonization and food migration that occurred long ago.
Though there are obvious differences among the local cuisines in West Africa, there are also many commonalities, mainly in the ingredients used. Many dishes are enriched with a base of tomatoes, onions and chili peppers. Considered an essential and even "sacred" cooking technique in the region, the combination of these three ingredients sauteed in oil is analogous to similar concepts such as the holy trinity of Cajun and Creole cooking in the United States, sofrito used in the Spanish-speaking world, soffritto in Italy, and the mirepoix of France. The most prevalent cooking oil is palm nut oil, traditionally associated with the coastal regions and contributes a distinctive colour, flavour and texture to food, while shea butter is more commonly used in the Sahel. Called karité in French, which comes from the Arabic word ghartī, it is prized for the rich mouthfeel it imparts.
