Dig a shallow hole and cover it with a thick layer of sharp sand. Build a neat, low, circular wall of carrots, packed in tightly. Stack the carrots with their necks facing outwards.
Continue adding carrots, building them up to a pyramid.
Insulate the carrots with a 30cm thick layer of clean straw. In cold areas, add a layer of soil for extra frost protection. Cover with plastic sheeting.
