Sweet Potatoes with Lime
Sweet potatoes and yams are virtually inter-changeable in the kitchen. Sweet potatoes have pale-yellow, dry, nutty-flavored flesh. Jewel and garnet are the two most common kinds of yam; both have reddish to purple-colored skin and brilliant orange, sweet, moist flesh. Look for firm, unblemished sweet potatoes or yams. They continue to sweeten after harvest, but they don’t store well and they tend to spoil fairly quickly. Wash them and roast them whole in the skin or peel them to roast, steam, or fry.
