How to Make Gari (cassava)
Gari is a fermented, dried cassava product that's a staple across West Africa. Fresh cassava is grated, fermented, pressed, and roasted to create tangy granules that can be eaten as porridge, soaked in water, or added to dishes. It stores well and provides essential carbohydrates.

History
Gari production developed in West Africa as a way to safely process cassava, which contains toxic cyanogenic compounds. The fermentation breaks down these toxins while developing flavor. Portuguese traders may have introduced cassava from South America in the 16th century, with African innovations creating gari.
Ingredients
- 10 lbs (4.5kg) Fresh cassava roots — Yields about 3-4 lbs (1.4-1.8kg) of finished gari.
- Optional Palm oil — Used to create 'yellow gari' and adds vitamin A.
Equipment
- Grater or grating machine
- Fermentation vessel or bags
- Press or heavy weights
- Large shallow pan for roasting
- Wooden paddle
- Sieve
Instructions
Ferment and Press
Pack the grated cassava mash into porous sacks (traditionally jute or polypropylene). Tie the bags tightly and place them under heavy weights or in a mechanical press. Allow to ferment for 2-5 days while the weights continuously squeeze out the liquid.
Time: 2-5 days
Tip: This simultaneous pressing and fermentation is critical; the liquid being expelled contains the majority of the toxic cyanogenic glucosides. Ensure the liquid can drain away freely.
Fermentation Timeline
- Day 1: Preparation — Cassava peeled, grated, packed for fermentation.
- Days 2-3: Fermentation — Sour aroma developing. Liquid releasing. Texture changing.
- Days 4-5: Full ferment — Strong tangy smell. Ready for pressing.
- Day 5-6: Processing — Pressing, sieving, and roasting into final gari.
Signs of Success & Spoilage
Good signs
- Sour, tangy aroma during ferment
- Dry, granular texture after roasting
- Golden or creamy white color
- Swells significantly when soaked in water
- Pleasant tangy taste
Warning signs
- Rotten or putrid smell
- Visible mold during fermentation
- Burnt taste after roasting
- Mushy texture
- Noticeably bitter taste (indicates residual cyanide due to insufficient fermentation/pressing)
Troubleshooting
- Gari not crunchy
- Cause: Not roasted enough or still wet Solution: Continue roasting until completely dry. Press more thoroughly.
- Burnt taste
- Cause: Heat too high or not stirring enough Solution: Lower heat. Stir constantly.
- Bitter taste
- Cause: Insufficient fermentation or pressing Solution: Ferment longer. Press more thoroughly.
Storage
Store in airtight container Keeps 6 months to 1 year at room temperature. Must be completely dry for storage. Any moisture causes spoilage.
