Kunun Zaki – Northern Nigerian Fermented Millet Probiotic Drink

How to Make It

1. 1

   Soak and Ferment the Millet

   Place the 400g of washed pearl millet into a large clean bowl or clay pot. Add the chopped sweet potato, sliced ginger, guinea pepper, and cloves. Pour in 1500ml of clean filtered water until all ingredients are fully submerged. Cover loosely with a clean cloth (not an airtight lid) and leave at room temperature to ferment for 24 to 48 hours. In warm Nigerian weather (28–35°C), 24 hours is usually sufficient. The mixture is ready when it smells pleasantly sour and tangy.

   Tip: Use a clay pot or glass bowl for best fermentation results. Avoid metal containers as they can interfere with the live cultures. Longer fermentation (48 hours) increases probiotic content but makes the drink more sour.

   Separate and Blend in Stages

   After fermentation, drain off and reserve the soaking liquid (this liquid contains wild yeasts and beneficial bacteria – do not discard). Separate the softened millet from the ginger, sweet potato, and spices. First, blend the ginger, sweet potato, cloves, and guinea pepper with 200ml of the reserved soaking liquid until very smooth. Strain this spice paste through a fine sieve or muslin cloth and set the liquid aside. Next, blend the fermented millet in batches, adding 400ml of fresh filtered water gradually until you achieve a smooth, fine slurry.

   Tip: Blending in stages ensures a smoother final drink. A high-powered blender gives the best texture, but a traditional grinding stone (dutsen niƙa) gives the most authentic flavour.

   Combine, Strain, and Cook

   Mix the millet slurry together with the spiced liquid and the reserved fermentation water in a large pot. Stir well to combine everything evenly. Pour the mixture through a fine muslin cloth or very fine sieve into a clean cooking pot, squeezing firmly to extract all the liquid and discard the dry chaff. Place the strained liquid over medium heat and stir continuously for 8 to 10 minutes until the mixture thickens slightly to a smooth, pourable consistency. Do not allow it to boil vigorously – gentle simmering preserves the nutrients.

   Tip: Continuous stirring is essential to prevent lumps and scorching at the bottom of the pot. The brief cooking step also makes the drink safer while retaining most of the beneficial compounds.

   Sweeten and Adjust Consistency

   Remove from heat and allow to cool for 5 minutes. Stir in the date palm sugar or honey while the drink is still warm so it dissolves fully. Taste and adjust sweetness according to preference and dietary needs – for diabetes management, use the minimum amount or omit entirely. If the drink is too thick, add the remaining 200ml of filtered water and stir to reach your preferred pourable consistency. It should coat a spoon lightly but flow freely like a thin porridge drink.

   Tip: For diabetic clients, replace sweetener with a small ripe banana blended in during the millet stage to provide gentle natural sweetness alongside potassium and resistant starch.

   Chill and Serve

   Transfer the Kunun Zaki into clean glass bottles or a ceramic pitcher. Refrigerate for at least 2 hours before serving – this drink is best enjoyed well chilled. Serve in tall glasses over ice if desired. Give the container a good stir or shake before each pour as natural separation will occur. Consume within 3 days when refrigerated for optimal probiotic benefit and food safety.

   Tip: For a gut-health boost, serve alongside a light meal such as masa (rice cakes) or boiled groundnuts. Shake well before serving as the natural starches will settle at the bottom during storage.
