My way is foolproof: wrap each individual potato in Egyptian cotton (the higher the thread count the better), 3 layers are better than one or two; then keep in a dark, unheated garage or outhouse, and then most importantly, make sure that each potato is at least 2 metres away from it's nearest neighbour - in that why, although they have eyes, and can therefore see, they do not have ears (they are not corn), and potatoes are so softly spoken that with that safe distance, they cannot hear when any of the other potatoes start talking about it being time to sprout (sprout as in putting out shoots, nothing to do with Brussels), so most of your spuds - that is short for (Christmas)s Puds - will stay nice and fresh for your roast dinner tomorrow. Happy Christmas all
