Honey never really goes off, so why keep it in fridge? When you keep honey at such low temperatures, they crystallize and form sugary-crystalline goop. It won’t spoil it but then you will need to thaw it and wait until it reaches its original consistency before using.
If you have a habit of throwing away the coffee jar in fridge, its time you should now stop doing that! Coffee powders absorb the nearby smell and fragrances when exposed to it for longer. You certainly do not want your coffee to smell like curry! Keep the coffee powder in an air tight container at room temperatures.
