Garnet sweet potatoes are slender, ovate and cylindrical in shape, tapering at the ends. Their rough skin, a dusty brown-maroon color, is the source of inspiration for Garnet yam’s namesake. When cooked the interior flesh is golden orange, starchy and moister than other yam varieties. Its flavor sweet with a savory earthiness will be at its sweetest when roasted, which allows the sugars of the yam to caramelize slowly. In addition to the tubers, the leaves of the Garnet yam plant are edible as well, offering both nutrients and a flavor similar to that of spinach.
