These traditional Congolese cassava sticks are made from naturally fermented cassava roots, pounded into a smooth dough, and wrapped in banana leaves before boiling. The natural fermentation gives them a subtle tangy flavor and a tender, slightly springy texture. They are a beloved staple street food across the Democratic Republic of the Congo, typically served alongside grilled fish, stews, or spicy sauces.

Ingredients
For the fermented cassava dough
- 3 lbs (1.4 kg) fresh cassava roots, peeled and cut into 2-inch chunks
- 8 cups (2 L) cool water, for soaking
- 1/2 tsp salt
For wrapping and boiling
- 4 large banana leaves, softened over an open flame
- 6 cups (1.5 L) fresh water for boiling
Directions
- Place the peeled cassava chunks in a large ceramic or food-grade bowl and cover completely with cool water. Cover loosely with a clean cloth and let ferment at room temperature for 3 to 4 days, changing the water once if it becomes very cloudy.
- Drain the fermented cassava and rinse thoroughly under cold running water. Transfer to a large mortar or food processor and pound or blend in small batches until a smooth, slightly sticky dough forms with no visible lumps.
- Sprinkle in the salt and knead the dough by hand for 3 to 4 minutes until elastic and uniform. The texture should resemble stiff mashed potatoes but feel slightly springy when pressed.
- Divide the dough into 4 equal portions of about 350 g each. Roll each portion between your palms into a smooth, thick baton shape roughly 8 inches long and 2 inches thick.
- Pass each banana leaf briefly over an open flame or dip it in hot water to make it pliable. Place one cassava stick on a leaf, wrap tightly, and twist or fold the ends to seal completely so no water can seep in during cooking.
- Repeat with the remaining sticks and leaves. Wrap each one tightly so the dough is fully enclosed in two layers of leaf.
- Place the wrapped sticks in a large pot and add enough water to cover them by at least 2 inches. Bring to a gentle boil over medium-high heat, then reduce the heat and simmer covered for 1.5 to 2 hours, checking the water level and adding hot water as needed.
- Carefully remove one stick and unwrap to test; the cassava should be firm, slightly translucent at the edges, and slice cleanly without crumbling. If still chalky in the center, re-wrap and cook another 20 to 30 minutes.
- Let the cooked sticks cool in their wrappers for 10 minutes before unwrapping. Slice crosswise into thick rounds and serve warm with grilled fish, palm oil stew, or any spicy Congo-style sauce.
Cook’s Notes
- Fermentation time is essential for both safety and flavor; under-fermented cassava retains naturally occurring cyanogenic compounds and will taste bitter and soapy.
- If fresh cassava is unavailable, frozen peeled cassava can be used and will need only 1 to 2 days of soaking since some natural fermentation has already begun.
- Wrap the leaves or foil very tightly so the cassava steams in its own moisture rather than sitting in water, which would make it soggy.
- Leftover sticks reheat well: rewrap in fresh leaves or foil and steam for 15 minutes, or pan-fry slices in a little oil until lightly browned.
- For the smoky flavor typical of street vendors, after boiling unwrap the sticks and grill them over charcoal for about 5 minutes per side.
