Mustard is another one of those condiments that people generally just put in the fridge without thinking twice. But actually, there is no need to. Just like ketchup, mustard has a very high acidity content, so mustard is quite self-preserving.
Have you ever seen a restaurant refrigerate their mustard? Nope. So neither do you. It really boils down to personal taste. Some people like their mustard room temperature, while others prefer their mustard chilled. Make your decision wisely.
23. Stone Fruit
Stone fruits, such as peaches, apricots, nectarines, and plums ripen the best at room temperature. So, it’s best to avoid placing them in the refrigerator unless you’re not planning to eat them right away. But either way, let them ripen at room temperature first.
If stone fruits are left to ripen in the fridge then they can become victim to chill damage. When a fruit is left to ripen at temperatures below 50 degrees Fahrenheit, the ripening process stops altogether. The result is a mealy and flavorless fruit.
Another fruit that you should never put in the refrigerator is a tomato and there is scientific evidence to back it up. That’s right! New research recently confirmed that exposing the fruits to cold temperatures, such as a in a refrigerator, damages the flavor-enhancing cells.
Researchers are looking into genetically modifying tomatoes to prevent this from happening, but for now, if you want to preserve the flavor of your tomatoes, its best to keep them away from the refrigerator. Also, the window-sill is a good place for unripe tomatoes.
