starch, shoe polish, and a coffee substitute are just some of the more than
118 products that were made from sweet potatoes by George Washington Carver,
a famous botanist and educator. Sweet potatoes, a complex carbohydrate food,
are often thought of as "poor man's food" because they combine nutrition and
economy.
Sweet
potatoes and yams are not the same plant. The sweet potato originated in
Central and South America and is grown in the United States while the yam
was discovered in Africa and is imported from tropical countries. A sweet
potato is technically a "storage root." Yams are tubers. Sweet potatoes are
sweet and moist. Yams are dry and starchy. Sweet potatoes with orange
interiors have a high beta-carotene content. Yams have very little. Sweet
potatoes are grown in the United States. Yams are imported to the USA from
the Caribbean. The scientific name of sweet potato is Ipomoea batatas and
it's a member of the morning glory family. A yam on the other hand belongs
to the Yam plant family.
Unsolved mystery: Sweet potatoes were the principal food of the Moari, the
native people of New Zealand. How and when did the plant get from the
Americas to New Zealand, thousands of miles across the Pacific? It's a
gastronomic mystery.
The sweet potato is arguably the healthiest vegetable you can eat. This
super spud is packed with vitamins A (beta carotene), B6, and some C, as
well as potassium and fiber. The sweet potato ranks number 9 (out of 10
power-packed vegetables) for its concentration of vitamins and minerals.
(Broccoli is number 1.) It's as versatile a food as you can find - used in
main dishes, soups, desserts and even as a dip.
North Carolina is the "Sweet potato Capital of the World."
Sweet potatoes
may be baked, boiled,
broiled, mashed, stuffed, steamed, sautéed and cooked in the microwave. They
can be substituted for Irish potatoes, apples and squash in almost any
recipe. They are great raw - use them as a crudités, shredded on greens or
julienne for a colorful addition to salads.
Sweet potatoes make attractive houseplants. Place a sweet potato in a jar of
water with its narrow end down. Put the jar in a warm, dark place and keep
the jar filled with water. New roots will grow and in about 10 days, the
stem will grow. As soon as this happens, put the jar in a sunny window. As
the vine grows, it can be left to trail or trained to climb.
