Onions
Onions don’t just rely on warmer temperatures; they actually depend on bright and open-air circulation to stay fresh. Regardless of how you will choose to cook them, you need to look after them with care.
And strangely, they’re meant to be far from your potatoes since they can speed up the onions’ aging processes. So not only are they supposed to be out of the fridge, but they’re also shouldn’t be next to each other.
