I picked sweetpotatoes last Sunday and, indeed, i think the cold did them no favors. (After reading about chilling injury and looking at photos, yup, chilling injury.) I'm dehydrating a few trays of shredded sweetpotato. One symptom of chilling injury is the sweetpotatoes oxidize faster: yup. The shreds aren't appetizing looking, but probably will be OK in a casserole or something. Hate to loose the harvest. Well, "harvest".
