Highland farmers eat these tubers before heading to the fields each morning because they're considered slow-burning enough to power a full day of farm work.
Arrowroot corms and sweet potatoes are boiled or roasted whole over hot coals until soft inside with a slightly charred skin, then peeled and eaten by hand. They're sold at market stalls and roadside kiosks across Nyeri and Murang'a, usually alongside a cup of tea.
