More than 30 years ago, dark - skinned sweet potatoes with sweet bright -
orange flesh were introduced into the U.S. To distinguish them from the more
traditional tan - skinned variety of sweet potato with less - sweet light colored
flesh, the African word «nyami» referring to an edible root, was adopted in its English form «yam» and given to those dark - skinned sweet potatoes.
If using just sweet potatoes, find golden ones that retain their shape, rather than the
orange -
fleshed variety that are great for a
traditional mashed sweet potato casserole.
