Tomatoes
Never place your tomatoes in the fridge, it impacts the taste of the items, negatively. There is recent scientific research that suggests this is the case, anyway, and we want to give science as much credit as possible! We have all put tomatoes in the fridge before, and what can you report?
They do get weird and slightly less delicious. Researchers looked into genetically modifying tomatoes to prevent this but have not made any real breakthroughs as of now. Want to preserve the flavor of your tomatoes? Keep them out of the fridge and on the window-sill if they are unripe.
