If you’ve ever gone to grab a potato from your pantry only to find it sprouting, you know how frustrating it can be. Sprouted potatoes can become soft and unappetising, and while they’re not necessarily unsafe to eat, they’re best avoided. So, what’s the best way to keep potatoes from sprouting during storage?
Why Potatoes Sprout
Potatoes sprout when they’re stored in warm, bright environments or exposed to moisture. The sprouts, also called “eyes,” are the potato’s attempt to grow new plants.
While small sprouts can be removed before cooking, a heavily sprouted potato is often softer and less flavourful.
How to Prevent Sprouting
1. Store Potatoes in a Cool, Dark Place
The most effective way to keep potatoes from sprouting is to store them in a cool, dark, and dry location. The ideal temperature for storing potatoes is between 4°C and 10°C (40°F and 50°F). Too much warmth can encourage sprouting, while too much cold (such as in a refrigerator) can cause the potatoes to become sweet and gritty.
Best storage spots: A pantry, cellar, or cupboard away from direct sunlight are ideal locations for storing potatoes.
2. Keep Potatoes Away from Moisture
Moisture can encourage sprouting and cause potatoes to rot. Make sure your storage area is dry, and avoid washing the potatoes before storing them. If potatoes are wet, dry them thoroughly before placing them in storage.
3. Use a Breathable Container
Avoid storing potatoes in plastic bags, which can trap moisture and lead to rot. Instead, use a mesh bag, paper bag, or even a cardboard box. These materials allow air to circulate, keeping the potatoes dry and fresh for longer.
4. Separate Potatoes from Onions
Onions release ethylene gas, which can cause potatoes to sprout more quickly. To prevent this, store your potatoes and onions in separate areas. Keeping them apart will help extend the shelf life of both vegetables.
5. Check Your Potatoes Regularly
Even with proper storage, it’s a good idea to check your potatoes regularly for signs of sprouting or spoilage. Remove any sprouted or soft potatoes from the group to prevent them from affecting the rest of your batch.
