how to keep watermelon
Hereâs the kicker: Researchers have found that whole watermelons stored outside the fridge in a cool, dark place (around 55 or 60 degrees) last much longer than watermelons stored in the fridge (around 41 degrees). So, if youâve already got a whole watermelon in the fridge, you should keep it there. But if youâre storing it outside the fridge, put it in the fridge about three hours before you plan to eat it in order to cool it down to just the right temperature.
