The gourd used to ferment mursik, called a sotet, is charred and lined with soot from trees like African senna — a preservation method the Kalenjin have used for roughly 300 years.

Fresh milk is poured into a smoke-blackened calabash gourd and left to ferment for a day or more, taking on a smoky, tangy flavor from the charred lining. It's served in markets and homes across the Rift Valley in cups or bowls, often alongside ugali.

Why it's made this way: Mursik carries deep cultural weight for the Kalenjin — famous for producing many of the world's top distance runners — and it's served at nearly every major milestone from dowry negotiations to homecomings for champions.
