Amasi
South African Fermented Milk
A traditional South African fermented milk, Amasi, is a thick, tangy, and probiotic-rich beverage. It's naturally soured and thickened by beneficial bacteria present in raw milk.

๐ง Ingredients
- 2 liters (approximately 8 cups) Raw whole milk(Ensure the milk is fresh and raw for natural fermentation. Pasteurized milk will not ferment properly without a starter culture.)
๐จโ๐ณ Instructions
- 1
Prepare your container: Ensure a clean, non-reactive container is ready. Traditionally, a calabash (gourd) was used, but a glass jar, ceramic pot, or food-grade plastic container will work. Avoid metal containers as they can react with the milk during fermentation.
โฑ๏ธ 1 minute - 2
Pour the raw milk into the clean container. Fill it no more than three-quarters full to allow space for expansion as it ferments.
โฑ๏ธ 1 minute - 3
Cover the container loosely. This allows air to circulate while preventing dust or insects from entering. A clean cheesecloth secured with a rubber band, a loose-fitting lid, or a clean kitchen towel works well.
โฑ๏ธ 1 minute - 4
Ferment at room temperature: Place the container in a warm spot in your kitchen, ideally between 20-25ยฐC (68-77ยฐF). Avoid direct sunlight. Let the milk ferment undisturbed for 2 to 3 days. The exact time will depend on the ambient temperature and the natural bacteria present in the milk.
โฑ๏ธ 2-3 days - 5
Check for readiness: After 2 days, check the milk. It should have thickened considerably, resembling yogurt or a very thick cream, and developed a pleasant sour aroma. If it's still too liquid or not sour enough, continue fermenting for another day, checking periodically.
โฑ๏ธ Ongoing check - 6
Stir and serve: Once the desired consistency and sourness are achieved, stir the Amasi gently. It can be consumed immediately as is, or served with a meal. It has a tangy, slightly sour taste and a thick, creamy texture.
๐ก Pro Tips
- โNatural fermentation relies on the wild yeasts and bacteria naturally present in raw milk. The warmer the environment, the faster it ferments.
- โAmasi is a rich source of probiotics, beneficial for gut health.
- โThis is a traditional beverage enjoyed across South Africa, often as a staple accompaniment to meals.
โจ Twist Ideas
Inspiration for your own version of this recipe
- For a thicker Amasi, use milk with a higher fat content or extend the fermentation time slightly.
- For a more sour taste, allow it to ferment for an extra day or two, or use a slightly warmer fermentation temperature.
