Please pass the candied yams . . . uh, sweet potatoes . . . Oh you know . . . that melted-marshmallow-coated casserole of orange veggies bobbing around in a brown-sugar-and-butter bath.
Well, what are they? Yams or sweet potatoes?You're about to become enlightened regarding the difference between the two. And as a bonus, your newfound knowledge will prepare you for Thanksgiving dinner if the conversation begins to wane.
And . . . when waning sets in, you can quickly offer some interesting tete-a-tete by posing the question: "Did you know that a yam is a thick, tropical-vine tuber, having nothing whatsoever to do with a large musical instrument?"
Here's the scoop - real yams are large, fleshy root vegetables that have been cultivated in Asia since 8000 B.C. The tuber (yam) has a brown or black skin that resembles the bark of a tree and off-white, purple, deep orange or red pulp - usually sweeter, moister and denser than the sweet potato.
Yams are popular vegetables - though not so much in these parts - with more than 150 varieties throughout the world. They range from the size of a small potato to a massive 7 feet long and 120 pounds. These yams are often sold in Caribbean and most Latin American countries by the "chunk," measured by weight.
But here's where the confusion begins . . .
Food writers Jeannette Ferrary and Louise Fiszer explain the yam/sweet potato connection this way:
"For all practical purposes, it might be more intriguing to think of the yam and the sweet potato as twins separated at birth, growing up with different quirks and twitches but retaining the essential sweet nature that makes them virtually interchangeable from a culinary perspective."
It sounds as if they are saying that yams and sweet potatoes can be substituted for each other in recipes.
And there's much more:
- Yams contain a compound from which estrogen was first manufactured.
- What is labeled as a yam in our supermarkets is actually a sweet potato - probably a hybrid that was developed in Louisiana in the early 20th century.
- The name "yam" was used for selling purposes to set it apart from the sweet potatoes that are grown in North Carolina, which were not as sweet and not as moist and are stringier when cooked.
- The true yam is not even distantly related to the sweet potato.
- Yams are generally sweeter than the sweet potato.
And while we're dishing out these new yam/sweet potato tidbits, here's another whammy . . . sweet potatoes are not actually potatoes; they are members of the morning glory family. It wasn't until the 16th century that they were referred to as "potatoes."
Truth is . . . we've been eating sweet potatoes for years, perhaps thinking they were yams. No wonder sweet potatoes and yams have been confused with one another. In the South, sweet potatoes are often called yams. Even more mixed up is the canning practice of labeling sweet potatoes "yams."
We should probably focus on sweet potatoes since they're available and are considered a traditional Thanksgiving dish.
Consumers can purchase two types of sweet potatoes in this country. One is a pale variety and the other is a darker-skinned species that many of us erroneously have called "yams."
- Pale sweet potatoes have a thin, light yellow skin and flesh. When cooked, their texture is crumbly and dry, like a regular potato.
- The darker variety of sweet potatoes have a thicker skin and cook up vivid orange and moist.
- Choose firm sweet potatoes that are small to medium in size. They should be smooth and unblemished and free of soft spots.
- Sweet potatoes should be stored in a cool, dry, well-ventilated place for up to a week. Don't refrigerate. (In ideal conditions, sweet potatoes can be stored for up to four weeks.)
- After peeling raw, sweet potatoes, keep them from darkening by letting them sit in cold water to which lemon juice has been added (1 quart water mixed with 3 tablespoons lemon juice). Drain well before using.
- Sweet potatoes are more nutritious if cooked in their skins.
Well, there you have it, Pilgrim! You're ready to take those taters and slice and spice 'em so nobody can tell that they were originally sweet potatoes.
Finally, if you harbor the mind-set that sweet potatoes are just a Thanksgiving side dish . . . know this . . .
Baked sweet potatoes have a natural affinity for melted butter, maple syrup and freshly grated nutmeg.
It's guaranteed to stop any yammering!
