Potatoes remain a staple of British cuisine, whether boiled, mashed, roasted, wedged, or sliced. Proper storage is key to keeping them fresh for longer at home. When left in their original plastic packaging, potatoes often begin to sprout and develop a green tinge before use. Fortunately, this can be prevented by following simple food storage guidelines.
Fridge Storage Now Recommended
The Food Standards Agency's latest advice recommends storing potatoes in the fridge or a cool, dry place. Previously, experts cautioned against refrigeration due to health concerns, as cold storage was thought to increase levels of acrylamide, a compound associated with cancer risks. However, current guidance indicates that the fridge is perfectly suitable. Look for a chilled symbol on potato packaging as confirmation.
Tips for Refrigerated Storage
Ensure potatoes have adequate space to prevent bruising and keep them separate from moisture-heavy produce. A member of the Money Saving Expert Forum suggests using two distinct salad containers in the fridge: one for potatoes and other root vegetables, and another for peppers, tomatoes, lemons, limes, and softer vegetables. They explained, 'I take them out of any plastic bags or wrapping and put a layer of kitchen roll in the bottom to absorb any wetness.' Another forum member shared, 'I store mine in the fridge in a paper bag, and they last a bit longer than in the plastic bag they come in.'
Alternative Cool, Dry Storage
A cool, dry spot is equally effective for extended storage. According to a food specialist at The Kitchn, 'If you have a dark, cool closet away from the heat of the kitchen, store them there.' A pantry or cupboard works well, provided the temperature remains consistently below 10°C. Keep potatoes away from stoves and heating vents. Remove potatoes from plastic packaging and transfer them to a basket or breathable cotton sack. Ensure they are completely dry before long-term storage, as damp potatoes rot or sprout faster.
Darkness and Separation
Tesco highlights that darkness is ideal for potato storage, as light triggers photosynthesis and sprouting. They also advise storing potatoes away from other fresh produce, particularly onions, which release ethylene gas. 'This means that your fruits and veggies will ripen one another too quickly, so your potatoes should be stored separately to stop this.'
How to Cure Potatoes for Six-Month Shelf Life
According to Tesco, 'curing' healthy, unsprouted potatoes can prolong their lifespan for up to six months. Follow these steps:
- Select bulky potatoes with thick skin, ensuring no significant puncture marks, soft spots, mould, blemishes, or shovel damage.
- Brush off mud but do not wash potatoes, as moisture encourages sprouting.
- Place potatoes on a dark sheet of newspaper, ensuring they are not touching to allow air circulation. Leave them for two weeks.
- Store in a well-ventilated, cool, dry place below 10°C. Check every few weeks for sprouted or spoiled potatoes.
If a potato is severely shrivelled or has large, well-developed sprouts, it is best to discard it. By following these storage methods, you can keep potatoes fresh and reduce food waste.
