Potatoes should be stored in a cool, dry and dark place, like a cupboard. They should be stored away from onions, as they both release moisture which causes them to sprout faster.
Unwashed potatoes last longer than clean potatoes.
If your potatoes have sprouted they are still ok to eat, just chop the sprouts off. If your potatoes are going green, you need to cut off the green areas, or if they are really bad, then you should discard them. The green can indicate natural toxins that may not be destroyed by cooking.
Freezing: Raw potatoes don’t freeze well, but you can freeze cooked potatoes.
