Onions survive longer than other produce, but many people don't know how to preserve them.
These "storage" onions your usual red, white, and yellow ones are best stored in a cool, dry, and light-free environment.
Good news if your countertop fits this description! Similar conditions suit potatoes, but don't store them together.
Technically, they can, however refrigerating most onions causes two problems.
First, the cold of a refrigerator turns onion starch into sugar, making them mushy or soggy.
Remember that onions have likely traveled for a while before reaching a vegetable section.
When storing spring or sweet onions in the fridge, wrap each bulb in paper towels to absorb excess moisture, which can impair flavor and texture and speed up deterioration.
