Potatoes and Tubers

Potatoes and their fellow underground storage organs — sweet potatoes, cassava, taro, yams — are the world’s starchy workhorses. Their cooking behavior is governed by starch content and type, which determines whether the cooked result is fluffy and dry (mealy) or dense and moist (waxy). The potato is also a case study in how storage temperature quietly rewires food chemistry.

Potatoes

Central/South American native domesticated 8,000+ years ago. The tuber is a swollen underground stem tip, storing starch and carrying “eyes” (dormant buds). Mild earthy flavor comes from a pyrazine compound produced by soil microbes.
