Fermented corn dough (kenkey / banku dough) substitutes
Fermented corn dough (kenkey / banku dough) substitutes — 6 options, ranked, with the exact amount
Use Store-bought fermented corn dough (frozen or vacuum-packed)
Same amount as the fermented corn dough (kenkey / banku dough)
African grocers sell ready-made corn dough in tubs and vacuum packs, sometimes labelled kenkey dough or banku mix. It is the actual ingredient, already soured, and it saves you two or three days.
Masa harina plus acid is the fastest workable swap: for 2 cups of fermented dough, mix 2 cups masa harina with about 1 ¾ cups water plus 3 tablespoons plain yogurt, and rest it 30 minutes. If you have two or three days, plain fine white cornmeal mixed with water and 2 tablespoons of live yogurt, left at room temperature and stirred daily, is genuinely the real thing and needs no equipment. Cornmeal with buttermilk instead of water is the no-wait version and tastes mildly tangy rather than deeply sour.

Store-bought fermented corn dough (frozen or vacuum-packed)
similar taste and texture
African grocers sell ready-made corn dough in tubs and vacuum packs, sometimes labelled kenkey dough or banku mix. It is the actual ingredient, already soured, and it saves you two or three days.
- Best for
- kenkey, banku, akple, ogi and akamu, tuo zaafi
Read the label: banku mix is usually corn dough already blended with cassava dough, which is what you want for banku but not for kenkey. Keep it frozen, since it keeps souring in the fridge and will eventually go too far.
Masa harina plus yogurt or lemon juice
different taste, similar texture
The best fast option, because masa harina is already fine-milled corn that hydrates into a smooth cohesive dough rather than a gritty one, and the acid supplies an immediate tang.
- Best for
- banku, kenkey in a hurry, akple, when you have no time to ferment
What you lose is the deep, complex, faintly cheesy sourness that days of lactic fermentation builds; the yogurt version tastes sour on the surface only. Masa is also nixtamalized, so it carries a distinct lime-treated corn aroma that reads Mexican rather than Ghanaian.
Fine white cornmeal fermented at home
similar taste and texture
This is not really a substitute, it is the traditional method with a shortcut starter. Mix fine white cornmeal with warm water to a thick batter, stir in live yogurt or the liquid from a previous batch, cover loosely, and stir once a day until it smells sharply sour.
- Best for
- kenkey, banku, ogi and akamu, anyone who wants the real flavour
Needs nothing but a bowl and time, and the flavour is genuinely right, which no same-day method achieves. Ferment somewhere warm, around 75 to 85 F; a cold kitchen sours it slowly and can let it go musty instead.
Cornmeal plus sourdough starter discard
different taste, similar texture
A clever shortcut if you already keep a starter, because you are borrowing an established culture instead of waiting for one to establish itself. Sours the dough properly in under a day.
- Best for
- banku, kenkey, same-week fermentation
The sourness is real and well developed but comes with a wheat-bread aroma that is not part of kenkey's profile, and the discard makes the result no longer gluten-free. Use a mature, tangy starter rather than a young sweet one.
Cornmeal plus buttermilk, no fermentation
different taste and texture
The no-wait option that still tastes of something. Buttermilk brings immediate mild acidity and a little dairy richness, and it hydrates cornmeal into a slightly softer dough.
- Best for
- banku on a weeknight, akple, cornmeal porridges
The tang sits on top of the corn rather than running through it, and the texture is a little grainier and less stretchy than fermented dough. Good eating, clearly not kenkey.
Plain cornmeal with lemon or lime stirred in (honest least-bad option)
different taste and texture
You will end up with a firm maize porridge, essentially unfermented, closer to polenta or ugali than to kenkey or banku. It will be a decent starch to eat with soup or stew.
- Best for
- eating with soup or stew, when there is nothing else in the house
Nothing here reproduces the sourness that defines these dishes; the acid gives a bright surface tang, not depth. If sour maize is the whole reason you are cooking, ferment properly instead or buy ready-made dough.
Questions
5 questionsCan I use masa harina for banku or kenkey?
Yes, and it is the most reliable quick substitute. Masa harina hydrates into a smooth, cohesive dough that stirs up much like the real thing, and mixing yogurt or lemon juice into the water gives you a tang in half an hour. The difference is depth: fermentation builds a complex, almost cheesy sourness that added acid cannot imitate. Masa also brings its own nixtamalized corn aroma.
How long does corn dough take to ferment?
Usually one to three days at room temperature, and warmth is the main variable. In a warm kitchen around 80 F with a spoonful of live yogurt to start it, it can be pleasantly sour in 24 hours and properly sour in 48. In a cold kitchen it can take four days and is more likely to develop off flavours along the way. Stir it daily and taste from day one.
Can I use polenta or grits instead?
You can, with an adjustment in expectation. Polenta and grits are coarser and usually yellow, so the result is a coarser, sweeter, more obviously corn-forward mush, and it will not be smooth or stretchy. Fine white cornmeal is much closer to what Ghanaian corn dough is milled from. If coarse is all you have, grind it finer in a blender first.
Can I skip the fermentation entirely?
You can cook unfermented cornmeal dough and eat it happily with soup, but you will not have made kenkey or banku. The sour flavour is not a garnish on these dishes, it is their identity, in the same way sourness is the identity of sourdough bread. Adding acid at the end gets you a bright surface tang and none of the depth.
How do I know if my corn dough has gone bad?
Good fermenting dough smells sharply and cleanly sour, like plain yogurt or a sourdough starter, and looks uniformly pale with perhaps a little liquid on top which you can stir back in. Throw it out if it smells alcoholic, solvent-like or of ammonia, or if there is any pink, orange, black, blue or fuzzy growth on the surface. When in doubt, discard it; a new batch costs pennies.
Tips for substituting fermented corn dough (kenkey / banku dough)
5 tips- The banku and kenkey stir is a workout and it matters. Cook the dough over medium heat pressing and folding continuously with a stiff wooden spatula for 15 to 25 minutes, until it turns glossy, stretchy and pulls cleanly away from the pan. Under-stirred dough tastes raw and gritty.
- Kenkey traditionally has its dough split: half is par-cooked into a stiff aflata and then worked back into the raw half. That step is what gives the finished ball its texture, so do not skip it if you are following a kenkey recipe.
- Banku is corn dough plus cassava dough, usually around 3 parts corn to 1 part cassava. With corn alone the result is firmer and less stretchy, and 2 tablespoons of tapioca starch per cup of dough restores some of the missing stretch.
- Taste the dough as it ferments and stop when the sourness is where you want it, then refrigerate. It keeps souring in the fridge, just much more slowly, so plan to use it within a few days.
- Judge the ferment by smell. Sharply sour like yogurt or sourdough is right. Discard it if it smells alcoholic or solvent-like, or if you see pink, orange, black or fuzzy growth on the surface, and always cook the dough through before eating it.
