Says the chick who signed up to take roughly 32 semester hours of African Art History, culture and all......
As already mentioned, Africa is a HUGE continent, and there are as many cuisines there as here, and then some. Yes, a bit of research is necessary, but you CAN find something you will enjoy and even love.
Just like here, Africa and its cuisine has its share of external influences, starting with the Portuguese way back when on the upper Guinea coast (the area including Guinea Bissau, Guinea, Sierra Leone, Liberia, Cote d'Ivoire and Ghana.) At one point most of the European nations and the U.S. somehow decided to carve up pieces of Africa for themselves, so depending upon which country/region you're looking at, you will find Portuguese, Spanish, German, French, and yes, good-ole US influence. There were also significant Muslim invasions and take-overs in various areas, so you'll find Middle Eastern influences as well. Anyone heard of Creole? Yes, the original Creole comes from Africa. You ever barbeque over an open fire? Yep, that's technically African, too.
Needless to say, you will find recipes that are a blend of the traditional ethnic group foods plus whatever other country influenced a particular area. So again, you CAN find something within your comfort zone that you will like, and maybe even love. When searching, I'd recommend trying to narrow down your search - pick a country (such as Ethiopia as Dan has mentioned) or even an ethnic group name and search with those rather than just "Africa." If you have a particular European or other non-African cuisine you like, and aren't sure where you might find that country's influences in Africa, feel free to PM me and I'll be happy to help.
