Cold temperatures can turn the starch in potatoes into sugar, leaving them discoloured and tasteless. Potatoes should be stored unwashed and at room temperature, in a spot far away from any sunlight. If possible, keep them in a burlap sack until you're ready to use them. Note that potatoes release ethylene gas, which can make other fresh ingredients ripen too quickly – so they're best kept separately, if possible.
