Koko da Kosai (Fermented Corn Porridge and Bean Fritters)

Koko da kosai (Hausa for fermented corn porridge and bean fritters) is a beloved traditional breakfast widely eaten across Northern Nigeria and parts of West Africa. It is especially common among the Hausa-speaking people. The meal consists of two main elements:
Ingredients
For the koko
- 1 cup millet grains (also known as jiƙo)
- 2 cups water (for mixing)
- 2–3 cups boiling water (for cooking)
- ½ teaspoon ground ginger (citta)
- ½ teaspoon ground cloves (kanumfari)
- ¼ teaspoon black pepper or chile powder (optional)
- ½ teaspoon potash (kanwa; optional)
- Sugar (optional)
- Powdered milk (optional)
For the kosai
- 1 cup black-eyed peas (wake), soaked overnight and peeled
- ½ medium onion, finely chopped
- 1–2 fresh chili peppers, chopped (or to taste)
- Salt
- Water
- Vegetable oil
Steps
Koko
- Place millet in large bowl. Cover with large volume of cool, clean water. Soak 1–2 days to ferment slightly, changing water daily.
- Rinse and drain millet. Grind to smooth paste with 2 cups water in blender.
- Strain paste through fine sieve or cheesecloth. Discard chaff. Keep liquid starch mixture (koko base).
- Transfer koko base, potash, ginger and cloves to pot over medium heat. Cook, stirring continuously, until thick, smooth porridge. Remove from heat at creamy consistency.
- If desired, add sugar or milk to taste.
Kosai
- Cover black-eyed peas with cool water. Soak 4–12 hours. Drain. Peel skins.
- Blend peeled beans, onion and just enough water into smooth, thick purée. Do not make too watery.
- Stir in salt and chili pepper.
- Heat enough vegetable oil for deep frying in deep frying pan over medium-high heat.
- Scoop small portions of batter into hot oil with spoon. Fry until golden brown on both sides, about 2–3 minutes per side.
- Remove with slotted spoon. Drain on paper towels.
- Serve kosai with koko.
Notes from the original
- The koko porridge is traditionally made with guinea corn or millet in some regions, but fermented maize is also widely used.
- Potash helps the porridge thicken quickly and adds a distinct flavor, but it can be omitted or replaced with baking soda for a milder taste.
- Kosai is best when crispy on the outside and soft on the inside. Ensure the oil is hot enough before frying to prevent sogginess.
- For fluffier kosai, beat the bean batter thoroughly to incorporate air before frying.
- Some enjoy adding groundnut or spicy sauce for extra flavor.
