Mataba is the most culturally embedded dish of the Comorian archipelago, eaten across Mayotte, the Comoros, and in Mahorais diaspora communities worldwide. At its core it is a labour of transformation: tough, slightly bitter raw cassava leaves are pounded or blended to a fine paste, then slowly braised in rich coconut milk until they melt into a thick, deeply green, velvety sauce with a flavour that is both earthy and sweet, faintly bitter and profoundly satisfying. The addition of dried shrimp or smoked fish — optional but traditional — gives the dish an umami depth that makes it addictive rather than merely comforting. Eaten always over steamed white rice, mataba is the dish Mahorais people crave most intensely when away from home. The critical technique question is how the cassava leaves are prepared. Fresh cassava leaves must be blanched before pounding to drive off the hydrocyanic glucosides present in raw cassava — these volatile compounds are fully destroyed by heat, but the blanching step is not negotiable for safety. The pounded paste then goes into a pot with fried garlic, and the long simmer in coconut milk is where the magic happens: as the coconut milk gradually reduces over 30–40 minutes, it emulsifies with the leaf paste, creating a sauce of rich, clinging consistency. Stirring during this process prevents sticking and ensures the coconut milk's fat incorporates evenly. The finished mataba should be thick enough to hold its shape when spooned — too thin and it floods the rice; too thick and it pastes. Getting this right requires patience and constant attention in the final 10 minutes of cooking.
Serves 4
Bring a large pot of unsalted water to a rolling boil. Add the cassava leaves and blanch for 5 minutes to destroy the naturally occurring cyanide compounds. Drain immediately and rinse under cold water to stop cooking. Squeeze out as much water as possible.
This step is not optional with fresh cassava leaves — do not skip it even for young, tender leaves.
Transfer the drained leaves to a large mortar or food processor. Pound or pulse until the leaves form a rough, fibrous paste with no large pieces remaining — this does not need to be perfectly smooth, but the leaves should be uniformly broken down to a coarse, dark green paste.
Heat oil in a heavy-based saucepan over medium heat. Add onion and fry for 5–6 minutes until softened and translucent. Add crushed garlic and stir for 1 minute until fragrant.
Tip the pounded leaf paste into the pan and stir well to combine with the onion and garlic. Cook for 8–10 minutes, stirring frequently, until the paste darkens slightly and dries out a little — this cooks off excess moisture and develops the earthy flavour.
The paste will spit and steam; keep stirring to prevent it catching on the bottom.
Pour in the coconut milk, stir to incorporate fully, and add the dried shrimp or smoked fish if using. Season with 1 tsp salt. Bring to a gentle simmer — do not boil hard, which can cause the coconut milk to separate.
Cook uncovered on low to medium-low heat for 30–35 minutes, stirring every 5 minutes, until the coconut milk has reduced and been fully absorbed into the leaf paste, creating a thick, cohesive sauce. The mataba is ready when it holds its shape on a spoon and pulling the spoon through the pot leaves a trail that closes slowly.
The last 10 minutes require constant attention — reduce heat if it starts to stick.
Taste carefully and adjust salt — dried shrimp can be quite salty, so check before adding more. Serve mounded over steamed white rice, with the rice underneath and mataba ladled generously on top.
Always blanch fresh cassava leaves before use — they contain naturally occurring cyanide compounds that are fully destroyed by 5 minutes of boiling, making the dish completely safe to eat.
Frozen cassava leaves (available in African and Asian grocers) are pre-blanched and do not need the blanching step; they are a convenient and legitimate substitute.
If using spinach, add it directly without blanching and reduce the simmering time to 20 minutes — spinach releases more water, so you may need to extend cooking to achieve the right thick consistency.
Rinse dried shrimp under cold water before adding to remove excess salt and any surface grit — otherwise the dish can become unpleasantly briny.
The dish should be finished at a low simmer, not a rolling boil — high heat causes the coconut milk's fat to separate, giving a greasy rather than creamy result.
Mataba ya kamba (with crab): stir in 200 g of cooked crabmeat in the last 5 minutes of cooking for a luxurious, celebration-worthy version.
Mataba végétarien: omit dried shrimp and add a teaspoon of miso paste dissolved in a little warm water to provide the umami depth normally given by the dried seafood.
Mataba na viazi (with sweet potato): add 200 g of cubed cooked sweet potato in the last 10 minutes for a sweeter, more substantial dish.
Spiced version: add a bruised lemongrass stalk and 2 kaffir lime leaves to the coconut milk for an aromatic Southeast Asian-influenced variation popular in Mayotte's coastal towns.
Mataba keeps well covered in the refrigerator for up to 3 days; the flavour deepens as it sits. It thickens considerably when cold — reheat gently over low heat with a tablespoon of coconut milk or water to loosen. It freezes well for up to 2 months, making it ideal for batch cooking.
Mataba is one of the oldest documented dishes of the Comorian archipelago, with roots in the broader East African and Swahili coast tradition of cooking leafy greens in coconut milk — a technique found from Mozambique to Madagascar. The dish is considered the national dish of the Comoros and is deeply embedded in Mahorais identity. Cassava itself was introduced to the region from the Americas via Portuguese trade routes in the 16th century and quickly became a staple crop throughout the Indian Ocean islands.
Yes, when properly prepared. Fresh cassava leaves contain hydrocyanic glucosides which are toxic when raw, but these are fully destroyed by blanching in boiling water for 5 minutes. After blanching, the leaves are completely safe. Frozen cassava leaves sold commercially are always pre-blanched. Spinach can be used as a substitute without any special preparation.
Fresh cassava leaves are available at African, Caribbean and some Asian grocery stores. Frozen cassava leaves are more widely available and sold in bags at most African food shops. If neither is accessible, fresh spinach works well as a substitute — the flavour is milder but the technique and creamy coconut result are very similar.
Yes, and it is often better the next day when the flavours have had time to develop. Refrigerate covered for up to 3 days. The dish thickens significantly as it cools, so add a splash of coconut milk when reheating and stir well over gentle heat.
Yes — simply omit the dried shrimp or smoked fish. The dish will be milder in flavour, so consider adding a teaspoon of white miso paste or a small piece of kombu to the simmering coconut milk to provide some background umami depth. The result is a beautiful, naturally vegan dish.
The coconut milk needs to reduce fully and be absorbed into the leaf paste over 30–35 minutes of gentle simmering. If the dish is too thin, simply continue cooking uncovered over medium-low heat, stirring frequently, until it reaches the thick, spoonable consistency. Covering the pot traps steam and prevents reduction.
