This gumbo dish is another story of migration and change. It starts in Senegal and then moves on to South Carolina and Louisiana before coming up to Harlem. The roux is at the heart of every good gumbo, and this one uses dried shrimp, which is a touch of Senegal. The shrimp gives it an oceany umami flavor that you wouldn’t traditionally get in a Southern gumbo or a Louisiana gumbo. Louisiana comes out in the richness of the roux as you add spices. But unlike Louisiana gumbo, this dish is more about the soup than the rice, so it’s poured on top of the rice like it’s done in South Carolina. —From BETWEEN HARLEM AND HEAVEN
