To peel yams or sweet potatoes
easily, take them from the boiling water and immerse immediately in very
cold water. The skins will almost fall off by themselves.
Sweet potatoes contain the same
number of calories as white potatoes. However, they contain more vitamin
C and three times the beta-caroteen as white potatoes.
Yams do not have the same
nutritional value as sweet potatoes. They are about 10-20% less overall.
The best way to tell the
difference between yams and sweet potatoes is to look at the flesh,
which should be orange in a sweet potato, not red. Many sweet potatoes
are labeled yams by supermarkets.
Yams are less sweet than sweet
potatoes and the best sweet potato is called a "boniato" or "Cuban Sweet
Potato" and has a very light yellow flesh.
Sweet potatoes have 10 calories
per ounce less than yams.
Store them in a cool dry place,
not the refrigerator.
