How To Keep Potatoes Fresh For Longer in South Africa

1. Keep them in a cool place

Raw potatoes will thrive in a cool, dark place. The ideal temperature range is 43-50°, which is slightly above refrigerator temp. During cooler months, storing potatoes in an unheated basement or an insulated shed is a great idea.

It’s a bit tougher to store potatoes in the summertime, but use your common sense—instead of putting them next to a window, keep them in the area of your house that stays the coolest.

 Avoid areas with lots of light.

Exposure to light can cause your potatoes to produce chlorophyll and turn prematurely green.

While this color change is usually harmless, excessive sunlight can also cause potatoes to produce a toxic chemical called solanine. Ingesting solanine in high amounts can cause unpleasant side effects like nausea, diarrhea, and vomiting.

Don’t wash them before you put them away.

Step away from the sink! It’s best to keep potatoes as dry as possible if you’re trying to make them last. Moisture promotes the growth of fungus and bacteria—so wait to wash them until right before you use them.

Let them breathe.

Prevent moisture accumulation by allowing your potatoes plenty of airflow. If you store them in a tightly sealed container (like a ziploc bag), the moisture released by the potatoes will have nowhere to go.

How do you cure potatoes for long term storage?

Cure potatoes at a temperature of 45 to 60 degrees Fahrenheit and high relative humidity (85 to 95 percent) for two weeks. Healing of minor cuts and bruises and thickening of the skin occurs during the curing process. Once cured, sort through the potatoes and discard any soft, shriveled, or blemished tubers.
