Before storing spuds, look them over and use any bruised ones first. Since dampness
can cause decay, it is best not to wash spuds before storing.
Store Idaho Potatoes in a cool, dark and well ventilated place. They will keep
about a week at room temperature and for several weeks at 45 to 50 degrees Fahrenheit.
However, refrigerator temperatures are too low, which converts the potato's
starch into sugar, resulting in a sweet taste. . The extra sugar also causes
potatoes to darken prematurely while frying. (This process can sometimes be reversed
by storing the potatoes at room temperature for a week to 10 days.) If
potatoes have green patches, cut them off, as they have been exposed too
long to direct lighting and will have a faintly bitter taste. The rest
of the potato will taste fine.
Potatoes are still alive when they are picked, so they should be kept in a
cool area, away from the light. A cellar is ideal, but any place where they
won't be exposed to excessive heat or light will help prevent spoiling.
