Ideally, potatoes should be stored in a cool garage or basement where the relative humidity is 90% and the temperature is between 40- and 45-degrees F. Although they can be stored for long periods of time in temperatures below 40-degrees F, the starches begin converting to sugars which alters the flavor of the potatoes. If this happens in your storage area,
keep the potatoes at room temperature for two to three days prior to consuming and the desired flavor should return. If stored above 45-degrees F for prolonged periods of time, the potatoes will begin to sprout. Potatoes will become soft and shriveled if the relative humidity is too low. Storing potatoes in perforated plastic bags will help maintain higher humidity levels.
