Eru

What it really is

A Cameroonian leaf stew of finely shredded eru and waterleaf, often with smoked fish or meat.

Eru is a leafy stew named for the finely cut leaves of the forest vine Gnetum, also called okok in some Cameroonian contexts. The leaves are tough and fibrous, so they are sliced very thinly before cooking. Common ingredients include waterleaf (or spinach), red palm oil, smoked fish, beef, beef skin and crayfish. The combination is not a fixed recipe: cooks choose proteins and seasonings according to availability and preference, and some versions omit one or more of the fish or meat additions.

The dish is particularly associated with Cameroon’s Southwest. It is built from finely shredded eru leaves, another leafy green such as waterleaf, and red palm oil, with fish or meat often added. Water fufu is a customary accompaniment. The defining distinction from other leafy stews is the texture and structure of the finely cut Gnetum leaves; it should not be reduced on a menu to generic spinach stew.

Eru is usually cooked until the greens soften and the mixture becomes a moist, cohesive stew. Waterleaf releases liquid as it cooks; recipes may also use some cooking liquid from meat or fish. Because the leaf is cut into narrow strips, the finished dish has a different texture from a purée or a stew made with whole leaves. Red palm oil contributes colour and richness. Smoked fish and dried crayfish, when included, add a strong savoury flavour, while beef or skin contributes a different texture. These are choices to confirm rather than ingredients to assume in every serving.

How it's served

• Serve hot with water fufu or another cassava staple.
• Keep the greens moist and identify the proteins separately, since smoked fish, crayfish and beef combinations differ.

How to write it on the menu

• State which fish, shellfish or meats are included; recipes vary.
• Identify whether the greens include waterleaf, spinach or another local substitute, and whether the kitchen uses fresh or dried eru leaves.
• Do not describe every version as containing crayfish or beef skin; those are common possibilities, not universal ingredients.
