The Sweet Potato vs. The Yam
By Jennifer A. Wickes
It seems that most people get confused as to what is a sweet potato
and what is a yam! In fact, in the United States, most people use
both terminologies to refer to a sweet potato, when neither of these
two vegetables is related!
The sweet potato is found in tropical America and is a part of the
Morning Glory family.
The yam is a tuber (a bulb) of a tropical vine found in Central &
South America, as well as the West Indies, Africa and Asia.
Varieties There are mainly two varieties of sweet potato. The pale
sweet potato has a very thin yellow skin with a bright yellow flesh.
This variety is neither sweet nor moist, but more the texture of a
white baking potato. The darker skinned sweet potato has a thicker
orange skin with a sweet moist flesh.
The true yam is not marketed or grown widely in the United States.
Where it is marketed, is usually in Latin American markets. A yam can
be as small as a potato and can grow as large as 7 feet and weigh
over 120 pounds! The flesh can range in color from off-white to
yellow to pink to purple! The skin color can be from off-white to a
dark brown.
Season: Both the sweet potato and the yam are available fresh from October through March.
How to Select: When trying to choose a sweet potato, choose a medium sized variety
with smooth unbruised skin.
You will want to choose an unblemished yam with unwrinkled skin.
Storage: Store your sweet potatoes in a dry, dark 55 degree F (12 - 13
degrees C) area for approximately a month. Otherwise, use your sweet
potato within the week. Never place a sweet potato in the
refrigerator.
Store your yam in a cool, dark, dry place up to 2 weeks. Never place
your yam in the refrigerator.
Nutritional Qualities:
Sweet potatoes have high Vitamins A and C.
Yams have higher sugar content.
Wine Pairings:
Depending on what you are serving with your yams or sweet potatoes
and as to how you are preparing it, try a Chardonnay, a Fume Blanc, a
French Colombard or a Syrah.
Spices:
Brown sugar, butter, cardamom, cinnamon, cloves, coriander, cumin,
ginger, lemon juice, lemon peel, mace, marjoram, nutmeg, orange
juice, orange peel, poppy seed, sage, savory, thyme.
Equivalencies:
1 pound fresh = 3 medium = 3 ½ - 4 cups cooked and chopped
Preparation:
A sweet potato can be prepared like a potato: baked, boiled, sautéed,
steamed, microwaved, or fried.
A yam can be prepared like a sweet potato!
