Saccharine potatoes, or Ipomoea batata, are native to South America, where they were domesticated at least 5000 years ago. They’re additionally prevalent in Polynesia, and radio carbon dating of saccharine potato remains in the Cook Islands places them at 1000 AD, with most researchers figuring they date back to at least 700 AD. The Peruvian Quechua word for saccharine potato is kumar, while it’s called the remarkably kindred kumara in Polyenesia, prompting notional theorisation that early South American voyagers genuinely introduced the tuber to the South Pacific. At any rate, they’re ambrosial, they’re eaten everywhere, and they have a lengthy tradition of being consumed by salubrious people.
