How to Make Ogi (akamu)
Ogi (also called akamu or pap) is a Nigerian fermented cereal porridge made from maize, sorghum, or millet. The fermented slurry is cooked into a smooth, tangy porridge that's a traditional breakfast and weaning food. It's light, digestible, and a comforting staple across West Africa.

History
Ogi production has ancient roots in West Africa, predating written records. It developed as a way to process and preserve grains while creating easily digestible nutrition, particularly important for infants. Today, it remains a cherished comfort food and is commercially produced while still made traditionally in homes.
Ingredients
- 2 cups (400g) Dried corn (maize) — White or yellow; or use sorghum/millet
- As needed Water — For soaking, fermenting, and cooking
- To taste Sugar — For serving
- Optional Evaporated milk — For serving
Equipment
- Large bowl for soaking
- Blender or grinding stone
- Fine mesh strainer or cheesecloth
- Fermentation container
- Pot for cooking
Instructions
Blend and sieve
Blend the soaked corn with fresh water until very smooth. Strain the mixture through a chiffon cloth or fine muslin bag into a large bowl. Squeeze the cloth firmly to extract all the starch, leaving only the dry chaff behind. Discard the chaff.
Time: 45 min
Tip: Standard kitchen sieves are too coarse; a chiffon cloth is essential for the signature silky texture. You may need to sieve the liquid a second time to ensure no hull fragments remain.
Ferment
Cover the bowl and let the starchy liquid sit undisturbed at room temperature (25-30°C) for 2-4 days. During this time, lactic acid bacteria will ferment the starch. The solid starch will settle at the bottom, and a clear, sour liquid (omimidun) will form on top. For safety and flavor, the paste should reach a pH of 3.8 to 4.5.
Time: 2-4 days
Tip: The sour water on top acts as a protective layer against mold. Do not stir the mixture during this period.
Decant and Store
Carefully pour off and discard the 'sour water' (omimidun) from the top of the bowl. The thick, white paste remaining at the bottom is the Ogi. You can scoop this paste into containers or keep it in a jar covered with fresh water.
Time: 10 min
Tip: If you find the Ogi too sour, you can rinse the paste by adding fresh water, letting it settle, and decanting again.
Fermentation Timeline
- Days 1-3: Soaking — Corn softening in water.
- Day 3: Blending and sieving — Extracting starch from corn.
- Days 3-6: Fermentation — Starch settling. Sour water developing. Tang increasing.
- Day 6+: Ready — Paste is fermented and ready to cook or store.
Signs of Success & Spoilage
Good signs
- Clean, sour aroma (lactic acid scent)
- White or creamy starchy sediment
- Clear or slightly cloudy supernatant water
- Smooth, clay-like paste texture
- pH level between 3.8 and 4.5
Warning signs
- Rotten or putrid smell
- Pink, black, or fuzzy mold on the surface
- Slimy or ropey texture in the water
- Bitter or chemical taste
Troubleshooting
- Lumpy porridge
- Cause: Added to hot water too fast or didn't stir Solution: Mix with cold water first. Stir constantly when adding to hot water.
- Not sour enough
- Cause: Under-fermented Solution: Ferment longer. Use warmer location.
- Too sour
- Cause: Over-fermented Solution: Ferment less time. Can mix with fresh starch to mellow.
Storage
Store the fermented paste in a sealed container covered with a layer of fresh water in the refrigerator. Keeps 2-3 weeks. To maintain freshness and prevent the paste from becoming excessively sour, decant and replace the covering water every 2-3 days.
