6 Helpful Tips For Storing Fresh Raw Potatoes

Potatoes are a staple in many households, and they’re certainly nutritious. They’re also easy to grow, which is yet another reason to love them. However, if you’re not careful with your potatoes, they can rot quickly and become unusable.

Here are some tips for storing fresh raw potatoes:

1. Store Them In A Cool, Dark Place Like A Pantry Or Cellar.

Don’t store them in the fridge because cold temperatures will cause the starch in the potatoes to turn into sugar — making them sweet instead of starchy — and possibly causing them to rot or sprout faster than normal.

2. Don’T Wash Your Potatoes Until Ready To Use.

Washing potatoes before storing them can leave bacteria on their skin that can cause them to spoil faster than normal.

3. Don’T Store Your Potatoes Next To Onions (Or Any Other Strong-Smelling Food)

Because it could cause your potatoes to spoil more quickly than normal due to the presence of ethylene gas emitted by these foods which cause potato skins to wrinkle and split prematurely during storage; use separate storage areas for each item if possible (such as different drawers or shelves).

4. Keep Potatoes In A Paper Bag.

This will absorb excess moisture and help prevent sprouting. The bag also acts as an air filter, which is important for preventing mold growth.

5. Keep Them Away From Fruits And Vegetables

That gives off ethylene gas — this causes many fruits and vegetables to ripen quickly, but it also causes potatoes to rot!

6. Do Not Store Potatoes In The Refrigerator

Because this will make them sprout sooner. The best way to store raw potatoes is in a dark place at room temperature, such as a pantry or closet. You can also store raw potatoes outside in a cool, dry area or earth mound.
