How to store potatoes: 3 tips to prevent them from sprouting

You bought a bag of potatoes, and a few weeks later, you find that they’ve started to sprout? Don’t panic! Poor storage encourages the appearance of sprouts, making the potatoes less appetizing and even toxic in some cases. Fortunately, there are simple solutions to avoid this problem and extend their shelf life. Here are three essential tips to keep your potatoes in perfect condition for longer!

Three little-known tips to keep your potatoes in perfect condition

The place where you store your potatoes plays a crucial role in their shelf life. Poor storage accelerates sprouting and affects their texture and flavor.

1. Store Them in the Right Place

Where to Store Them?

In a cool place: The ideal temperature is between 4 and 8°C. A cellar, garage, or unheated pantry is perfect.
Away from light: Exposure to light encourages the production of solanine, a toxic substance that turns potatoes green. Store them in an opaque container or cover them with a cloth.
In a dry, well-ventilated area: Excessive moisture promotes mold and rot. A wooden crate or wicker basket, which allows air circulation, is a good choice.

Mistake to Avoid:

Do not store potatoes in the refrigerator! The cold converts starch into sugar, making them too sweet and giving them a grainy texture.

2. Add an Apple to Slow Down Sprouting

An old grandmother’s trick is to place an apple in your potato stash. This is not a myth: apples naturally release ethylene gas, which prevents tubers from sprouting.

How to Do It?

Place one or two apples among your potatoes.
Use a wooden crate or cloth bag to allow proper air circulation.
Replace the apples as soon as they start to soften to maintain their effectiveness.

Bonus Tip:

Do not store potatoes with onions! These two foods produce gases that accelerate their mutual deterioration.

3. Check Regularly and Remove Sprouts as Soon as They Appear

Even under the best storage conditions, some potatoes may start to sprout over time. It’s essential to monitor your stock regularly and act quickly.

What to Do:

Inspect your potatoes weekly and immediately remove any that show signs of sprouting.
Cut off the sprouts as soon as they appear: If the potato is still firm and healthy, it remains edible after carefully removing the sprouts.
Avoid wrinkled, spongy, or green potatoes, as they contain higher concentrations of solanine and can be toxic.

Warning About Solanine!

This naturally occurring substance in potatoes becomes toxic in large quantities. Excessive consumption of sprouted or green potatoes can cause symptoms such as nausea, vomiting, diarrhea, and abdominal pain.

Summary of Best Practices

Store them in a cool, dark, and dry place (ideally between 4 and 8°C).
Use a wooden crate, wicker basket, or cloth bag for proper ventilation.
Add an apple to slow down sprouting.
Avoid the refrigerator and do not store them with onions.
Monitor and remove sprouts as soon as they appear.

Conclusion

By following these simple tips, you’ll extend the shelf life of your potatoes and reduce food waste. Enjoy your mashed potatoes, gratins, and homemade fries without any unpleasant surprises!
