Amasi

Amasi is a traditional Southern African fermented-milk drink of thick, tart, naturally soured milk — smooth and slightly lumpy, somewhere between drinking yogurt and buttermilk. Known as maas in Afrikaans, mafi or sethemi in Sesotho and by many other names across the region, it is made by leaving raw cow's milk to ferment, traditionally in a calabash gourd or hide sack, until it thickens and separates into curds and a clear watery whey. It is dairy-based, sharply lactic-sour and gently cheesy, eaten from a cup or bowl, poured over stiff maize porridge, or drunk on its own as an everyday staple.
