Sweet potatoes are not to be mistaken with yams,
even though the terms are often used interchangeably. Sweet potatoes
are the common red-brownish skinned root vegetables with sweet orange flesh
and semi-smooth skin; there is also a variety with yellow flesh, with a
taste resembling a mix of potato and apple. Yams usually have a rough
dark brown skin, similar in texture to tree bark, with a white, purple,
or red flesh. Yams do not have orange flesh--Sweet potatoes are one of the easiest vegetables to cook that taste
like candy without adding too much sugar.
