So, why shouldn't you store onions in the fridge? For starters, the cold temperature can convert the onions' natural sugars into a yucky, sweet flavor. Plus, onions are natural absorbers, so they might pick up unwanted odors from nearby foods - like last week's leftover fish (yuck!)
Onions are also prone to mold when stored in humid environments, like the fridge. And who wants to deal with a moldy onion - not exactly the most appetizing thing! Instead, try storing them in a cool, dry place with good airflow.
One quirky fact about onions: they're natural tear-jerkers! The compounds that make you cry when you chop an onion are also antimicrobial - which means they help keep the onion fresh for longer. Talk about a superpower!
