A moist, yellow-fleshed 'sugar yam' that defined Southern sweet-potato cooking for the first half of the 20th century. Sweeter and moister than the dry white types, it was the holiday-table standard before the orange cultivars took over.
Nancy Hall was THE sweet potato of Black Southern kitchens for two generations — the one your great-grandmother meant when she said 'yams.' Sweet potato pie history runs through this cultivar.
Yellow flesh signals moderate carotenoid content — between white and deep-orange types — converting to vitamin A for eye and immune health. The moist sugar-yam texture comes from a higher enzymatic starch-to-sugar conversion during curing, which paradoxically raises the baked glycemic index; cook-and-cool to recover resistant starch and butyrate. Potassium load (~450mg per medium root) directly counters sodium-driven blood pressure.
Cure 1-2 weeks for full sweetness. Excellent baked, candied, or in pie. To moderate the glucose impact, boil rather than bake (boiling yields a lower GI than dry roasting) and cool before eating.
