Ofe onugbu is a traditional soup originating from Nigeria. It's made with a combination of bitterleaf, cocoyam paste, red palm oil, dried fish, beef and tripe, crayfish, seasoning cubes, and a traditional seasoning called ogiri igbo. The ingredients are simmered in water over in a covered pot until the cocoyam lumps dissolve and the other ingredients develop a tender consistency.
The soup shouldn't be too thick, so it's recommended to add more water if ofe onugbu thickens too much. It also shouldn't be bitter, so bitterleaf should be well washed and squeezed before cooking, and the water in the soup should also be changed until there's not a trace of bitterness left.
