Do Onions Go in the Fridge?
Take a look at a detailed examination on Do Onions Go in the Fridge.
Here's why: When an onion is chilled, the cold, humid temperatures in a refrigerator convert the starch to sugars (the same happens with potatoes), and onions tend to become soft or soggy a lot faster. Plus, as you probably already know, they also skunk up your fridge and make everything smell or taste like onions.
