When I first settled down in sept the temperature was less than 10 degrees so I started putting my hard liquor at my ventilating window and the weather always cool it to the right temperature (except on sunny days).
Now that temperature hovers roughly around one degree on each side of the zero-mark, my whole opened packet of meatball takes the throne (even sunny days don't go above 3 degrees anyway); problem of having the pantry at the other end of the corridor solved, kinda.
