For years, Jon Butts and Debbie have raised at EcoFarm a mystery sweet potato, which I grew for the first time last year (in the wrong place, a rose bed which was CONSUMED by vines!). I just dug up my first two, slowly browned three slices, covered, in coconut oil with chopped fresh garlic and sea salt. EXCELLENT! This year I am growing them out back in two beds, in part to hopefully achieve weed control as a bonus.
