Why Do Boiled Potatoes Turn Black?

Answer

Potatoes occasionally turn dark after they are boiled. This dark colour change may be brought about by the conditions under which they were stored or grown. However, the discolouration does not affect flavour, texture or nutritional value. They will also discolour due to contact with aluminum or iron, so cook them in stainless steel pots.
