Foods That Should Never Touch Your Fridge (And Why)
Ketchup
Here’s another common condiment debate: where should you store your ketchup? While most of us keep it in the fridge after opening, the vinegar in the sauce can actually react badly to cold air over time.
To keep your ketchup tasting fresh longer and avoid that annoying runny, watered residue, it’s best to store it in the cupboard instead. The same advice applies to other condiments with a high vinegar content, so keep this in mind when stocking up on your favorites.
