What a surprise. Well of course Sierra Leone finished first and Liberia finished second in a Jollof Rice competition. Those countries are on the Rice Coast.
I am surprised Senegal didn't win it, because the Jollof people are from Senegal and they created the dish.

I am honestly surprised that Nigerians and Ghanians would be claiming ownership of a dish that is obviously from Senegambia. Nigeria and Ghana ain't on the damn Rice Coast and they are just making nasty knock off versions of the good stuff.
Fwiw, the a lot of African American rice dishes of Jambalaya, Gumbo and Hoppin John are offshoots of Jollof rice, which were obviously brought to the USA by people that were brought as slaves from the Rice Coast.
