Ghana — banku is associated with Fante and Ga people of coastal Ghana; the pairing with grilled tilapia is a southern Ghanaian tradition reflecting the coastal fishing culture
Ghana's definitive combo — a smooth, slightly sour fermented corn-and-cassava dough ball (banku) paired with whole grilled tilapia coated in a pepper-onion sauce and finished over charcoal. Banku is made by fermenting corn dough and cassava dough together for 1–2 days, then cooking the fermented mixture in boiling water while stirring vigorously with a wooden paddle (odam) until it becomes a smooth, elastic, glossy ball that pulls cleanly from the pot. The tilapia is scored, marinated in chilli-ginger paste, and grilled whole over charcoal, basted with the sauce during cooking. The combination — sour fermented dough ball against smoky-spiced whole fish — is Ghana's most celebrated pairing.
Lunch and dinner; eaten with right hand (no cutlery); the banku is torn into pieces, pressed into a cup shape, and dipped into the fish sauce; ice-cold Club beer or water; the combination of sour-fermented-starchy and smoky-spiced-fishy is the definitive Ghanaian coastal flavour
{"The corn-cassava dough must ferment 1–2 days — fermentation develops the lactic acid that gives banku its characteristic sour note; unfermented banku is plain corn porridge","Cook banku over high heat while stirring continuously — the dough must be worked without pause for 20–25 minutes; stopping allows it to stick and burn","Score the tilapia deeply (3–4 cuts per side) before marinating — the cuts allow the pepper-ginger paste to penetrate to the bone; surface marination washes off during grilling","Grill whole fish over direct charcoal with frequent basting — the basting builds up layers of caramelised pepper sauce on the exterior"}
Add a small amount of okro (okra) to the banku pot in the last 5 minutes of cooking — the mucilage from the okra contributes an additional glossy smoothness to the dough and is a traditional Fante technique. The tilapia basting sauce should include a tablespoon of shito (black pepper-shrimp sauce) alongside the fresh pepper-onion mixture — the fermented shrimp note in shito adds depth that fresh pepper paste alone cannot provide.
{"Skipping the fermentation step — unfermented banku is called 'white banku' or 'fresh banku'; while edible, it lacks the defining sour depth of properly prepared banku","Continuous stirring without adequate heat — if the banku doesn't pull from the pot cleanly after 20 minutes, the heat is insufficient; adequate heat is essential for starch gelatinisation","Marinating the tilapia for less than 30 minutes — shorter marination leaves the chilli-ginger paste flavour on the surface only; it must penetrate the scored flesh","Grilling without basting — the basting is what builds the layered, caramelised exterior sauce"}
