Gambia vs Senegal jollof rice
Two origin stories. One river. One dish with two names.

Benachin (Gambia) and thieboudienne (Senegal) are the two oldest versions of the jollof rice tradition, both from the Senegambian region where the dish originated. They are closely related — both use a tomato-fish base and rice cooked in that base — but benachin is cooked in a single pot to complete absorption (more similar to pilaf), while thieboudienne poaches the fish separately and cooks the rice in the remaining stock. The Gambia and Senegal share the Jolof Empire heritage, and both dishes are legitimate claims to the origin.

The comparison
Technique
Single-pot — fish and rice cook together with the tomato base from the start
Watch out: Less depth of fermented flavour than Senegalese version
Fish poached in tomato base, removed, rice cooked in remaining stock, fish returned on top
Watch out: Complexity makes it harder to reproduce outside West Africa
The verdict
Both are the original. The Gambia and Senegal share the Wolof heritage. The dish has two names for the same ancestor.
The river Gambia runs through the middle of Senegal. The Gambia (the country) is surrounded on three sides by Senegal. The Wolof people whose Empire gave jollof its name live in both countries. To declare one country's version the original over the other is to ignore the geography. Benachin and thieboudienne are regional variants of the same dish, from the same people, in the same historical territory.

Questions
What is benachin?
Benachin is the Gambian name for the one-pot rice dish that is the ancestor of all modern jollof. The name means "one pot" in Wolof. It is rice cooked with fish, vegetables, and a tomato base, all in a single pot. It is closely related to Senegalese thieboudienne and is one of the oldest forms of the jollof tradition.
Is Gambian jollof the same as Nigerian jollof?
No — they share an ancestor but are very different dishes. Gambian benachin uses fish (not chicken or beef), broken or long-grain rice cooked with the protein from the start, and has a less spicy profile. Nigerian jollof uses long-grain parboiled rice, chicken or beef, scotch bonnet, and aims for a smoke crust. The only thing they share is the one-pot tomato-base rice technique.
