Sweet Potatoes

The most common varieties are the dark orange-skinned type. Moist with bright orange flesh. The pale yellow type is drier and crumbly like a white potato.
The terms sweet potato and yam are sometimes used interchangeably, but they are not the same. True yams grow in tropical climates and are long and cylindrical, while sweet potatoes are short with tapered ends.
Store sweet potatoes in a dry, cool place, such as a cellar or pantry. Sweet potatoes bruise easily so handle them with care.
You can substitute sweet potatoes for white ones in almost any recipe.
