A Note on Storage for All Potatoes
Always avoid temperature extremes when storing potatoes: if you keep your spuds in the fridge, their starch will turn to sugar; stored in a warm spot, they will sprout. Also, don't keep your potatoes with your onions — the onions will coax the potatoes into rotting.
Storing Mature Potatoes
Your best bet for storing potatoes is to keep them in a cool, dry, and well-ventilated place. They should last for several weeks. At 50 degrees, they can last for up to 3 months.
Storing New Potatoes
Store young potatoes in a cool, dry, and well-ventilated place, and use them within a week of purchase.
Storing Sweet Potatoes
Sweet potatoes are more perishable than potatoes. They should keep for 7 to 10 days when stored in a dark, cool, well-ventilated place. If kept at temperatures higher than 60 degrees, they will sprout and ferment, and the flesh may turn woody.
