Tips for Storing Potatoes in the UK
Potatoes are vegetables that can be used in various dishes. They can also be stored for later use, but it is important to store them properly.
One of the most common challenges people have with potatoes is that they don’t know how to store them properly. Potatoes are best stored in a dark, cool place where they will not be exposed to light or extreme temperatures.
The best way to store potatoes is in a cool storage space where the temperature is between 45 and 50 degrees Fahrenheit. Keeping potatoes at this temperature will help them stay fresh for two to three months.
If you are storing potatoes for the winter, it is important to check on them periodically to ensure they are not showing signs of spoilage.
Spoiled potatoes will have a sour smell and will be discoloured. If you find that your potatoes are beginning to spoil, it is vital to use them as soon as possible or discard them.
It is also important to keep your harvested vegetables away from other vegetables when storing potatoes. This is because potatoes give off a gas that can cause other vegetables to spoil.
Also, inspect for pests and insects. If you find any pests or insects on your potatoes, it is important to discard them.
