Banku, fermented corn dough balls

This ghana banku recipe turns fermented maize and cassava dough into smooth, tangy balls with a soft, stretchy bite. The dough is mixed, left to ferment for two to three days, then kneaded in the pot until it pulls away from the sides — that is when you know it is ready. One serving is about 275 g.

Banku is a staple of southern Ghana, most closely tied to the Ga-Dangme people of Accra, and its name is thought to come from Ga-Dangme words meaning food once stored wrapped in leaves. Corn kernels were traditionally soaked, milled into a wet dough with cassava, and left to ferment for days before cooking — the ferment gives banku its signature sour tang. It is eaten by hand, torn into pieces to scoop up soup, stew or grilled fish, and sold in chop bars across the country.

Pairs well with: Light soup or kontomire stew & grilled fish

The Heritage Formulary

Measured Ingredients

Cornmeal, yellow, whole-grain, fine 400g (14 oz)

Fine cornmeal ferments evenly. Substitute: White cornmeal, same weight.

How to choose: Choose fine, fresh cornmeal with a sweet, corn-like smell; stale meal tastes flat after fermenting.

How to prepare: Measure into a large clean bowl.

Required
Cassava flour 100g (3.5 oz)

Adds stretch and smoothness. Substitute: Finely grated fresh cassava, drained, 150g.

How to choose: Look for fine, dry cassava flour with no lumps or musty smell.

How to prepare: Sift if lumpy, then add to the cornmeal.

Required
Warm water 800ml (3 1/3 cups)

About 40°C (104°F) for mixing. Substitute: Room-temperature water (ferments more slowly).

How to choose: Use clean drinking water; very hot water kills the fermenting microbes.

How to prepare: Warm gently; do not boil.

Required
Salt 5g (1 tsp)

Fine salt. Substitute: Sea salt, same weight.

How to choose: Any fine table salt works.

How to prepare: Measure and set aside.

Required

Estimated cost: Low — about $1–2 per serving at home (USD)

Good banku is smooth and stretchy with a gentle sour tang, never lumpy or gluey.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 55m

Prep Stage: Mix and Ferment the Dough

20 Mins • Mixing + 2–3 Days Fermenting

Two to three days before you plan to cook, whisk the cornmeal, cassava flour and salt together in a large clean bowl, then add the warm water a little at a time, stirring until you have a smooth, thick paste like pancake batter. Cover loosely with a clean cloth and leave in a warm corner of the kitchen. Stir once a day. The dough is ready when it smells clearly sour and shows a few small bubbles — in a cold kitchen this can take up to five days, so judge by smell, not the clock.

Maestro Tip: A loose cloth cover, not an airtight lid, lets the ferment breathe; an airtight seal can trap gas and give off flavours.

1
Make the Slurry

5 Mins Room temperature, ~24°C (75°F)

Tip the fermented dough into a heavy pot and add about 250 ml (1 cup) of the water. Work it with your hands or a wooden spoon, squeezing the dough through your fingers until every lump is gone and you have a completely smooth, milky slurry. This one step is what keeps the finished banku lump-free.

If the slurry still feels grainy, add a splash more water and keep working it — lumps now will not cook out later.

Done when: The slurry is smooth, pourable and free of lumps.
2
Start Cooking

5 Mins Medium heat, ~160°C (320°F)

Set the pot over medium heat and start stirring at once with a sturdy wooden spoon, scraping the bottom and sides so nothing sticks. Within a few minutes the slurry thickens and starts to clump — keep stirring without stopping.

Do not walk away in these first minutes; the dough catches on the bottom fast once it starts to thicken.

Done when: The mixture has thickened into a soft, gloopy mass.
3
Knead in the Pot

15 Mins Medium heat, ~160°C (320°F)

Keep stirring and folding the dough hard for about 15 minutes, pressing it against the sides of the pot with the spoon. Add a splash of water, a quarter cup at a time, whenever it gets too stiff to move. The colour shifts from bright white to a slightly translucent grey, and the dough turns smooth, stretchy and heavy.

This is an arm workout — steady, unbroken stirring is what makes banku smooth instead of lumpy.

Done when: The dough is smooth, stretchy and pulls away cleanly from the sides of the pot.
4
Steam Through

5 Mins Low heat, ~120°C (250°F)

Turn the heat to low, sprinkle a tablespoon or two of water around the dough, cover the pot and let the banku steam for 5 minutes so it cooks right through. Give it one final vigorous stir to bring it together.

The short steam finishes the centre of the dough, which stirring alone can leave underdone.

Done when: The banku is cooked through, hot and evenly smooth.
5
Shape and Serve

5 Mins Hot, ~70°C (158°F)

Wet your hands with a little water, divide the dough into 4 equal portions and roll each into a smooth ball about the size of an orange. Wrap each ball tightly in plastic wrap or a clean damp cloth to hold the warmth, and serve at once with hot soup or stew.

Wet hands stop the hot dough from sticking to your palms while you shape it.

Done when: Four smooth, warm balls, ready to eat.

Finishing Touches & Plating

Serve the banku hot, straight from the pot, with the soup or stew ladled alongside so each person can tear off a piece and scoop with it. A small bowl of pepper sauce on the table lets everyone season to taste.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: B vitamins, magnesium and iron from the maize and cassava; fermentation gives the dough its gentle sour tang.

Slow, Steady Energy

About 98 g of carbohydrate per serving gives long-lasting energy, which is why banku is a working lunch across Ghana.

Naturally Fermented

The two-to-three-day ferment gives banku its gentle sour tang and is the traditional way the dough is prepared.

Naturally Gluten-Free

Made only from maize and cassava, banku contains no wheat or gluten, so it suits a gluten-free table.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Soups

Light Soup

Thin, peppery light soup is the classic partner: the soft banku soaks it up, and the soup's heat and spice balance the dough's mild sourness.

Sauces

Kontomire Stew

The rich, leafy kontomire stew clings to torn pieces of banku, so every bite carries greens, egusi and tomato together.

Sides

Grilled Tilapia

Smoky grilled tilapia with pepper sauce is the chop-bar favourite — the fish's crisp skin and heat contrast with the soft, mild dough.

Drinks

Sobolo (Hibiscus Drink)

A cold, tart hibiscus drink refreshes the palate between bites of the warm, dense dough.

Complete menu

Start with a ball of hot banku, a bowl of light soup with grilled tilapia, and finish with a cold sobolo hibiscus drink.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

A Second Heavy Starch

Banku is already very filling, so serving it with yam, rice or kenkey in the same meal doubles the starch and leaves most people uncomfortably full. Pick one starch and let the soup or stew do the rest. This is general guidance, not medical advice.

Sugary Soft Drinks

A large sugary drink with a dense carbohydrate meal adds a fast rush of sugar on top of an already energy-rich plate. Water or an unsweetened drink suits the meal better. This is general guidance, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

General adultsA satisfying, traditional lunch — one ball with soup or stew is a full meal.
ChildrenSuitable from age 3+; serve a smaller ball and let them tear pieces to dip in mild soup.
ElderlyVery suitable — soft, easy to chew and gentle on the stomach; serve with a mild soup.
Pregnant womenGenerally suitable; make sure the dough is cooked right through and serve with a well-cooked soup.
Breastfeeding womenGenerally suitable; the energy-dense dough helps meet the extra energy needs of breastfeeding.
AthletesA strong pre- or post-training meal: about 98 g of carbohydrate per serving, best paired with a protein-rich stew.
Weight gainA good choice — take a full ball with a rich stew and a second helping if you are still hungry.
Weight lossEnjoy a smaller ball, about half a serving, with a large portion of vegetable stew and plenty of soup.

Health Conditions — Adjust or Avoid

Conditions

DiabetesBanku is high in carbohydrate, so keep the portion to about half a ball and fill the rest of the plate with soup and vegetables. Ask your clinician about portion size.
High blood pressureThis recipe is low in salt, but the soup or stew served with it often is not — keep the accompaniments lightly salted. Ask your clinician about a suitable portion.
Kidney diseaseBanku itself is low in protein and potassium, but check the salt and protein in the soup served with it. Ask your clinician about frequency.
GoutBanku is low in purines, so the dough itself is not a concern — the soup or stew served with it matters more.
Stomach issuesUsually gentle, but the sour tang and a very spicy soup can irritate a sensitive stomach — pair it with a mild soup.
Cardiovascular diseaseA low-fat staple; keep the portion modest and choose a light, vegetable-based soup over a very oily stew.
Fatty liverKeep the portion modest and favour vegetable soups over rich, oily stews with the banku.
Food allergiesContains no common allergens — no wheat, gluten, egg, milk, nuts or fish in the dough itself. Check the soup or stew served alongside for allergens.
Special therapeutic dietsNaturally gluten-free and low-fat; if you follow a prescribed low-carbohydrate diet, keep the portion small and ask your clinician.

If you have a medical condition, consult your doctor before changing your diet.

Storage & Use

How to store: Cool, then wrap each ball tightly in plastic wrap or a clean damp cloth and store in an airtight container.
In the fridge: 3 days, wrapped.
In the freezer: 2 months, wrapped in plastic and sealed in a freezer bag.
How to reheat: Steam or microwave with a sprinkle of water until hot right through, reaching 74°C (165°F); knead briefly to restore smoothness.
Freezing recommended: Yes — banku freezes well for up to 2 months.
Signs it has spoiled: Strong sour or mouldy smell, visible mould, or a slimy surface.
