Tuber Magnatum, also called the white Alba truffle or Piedmont truffle is to be found in northern Italy or the lower valleys of the Rhône. It likes growing near poplars and willows in calcareous-clay earth. Like the other white Italian truffle, Tuber Borchii, it outwardly resembles a potato (but the Magnatum is twice the size of the Borchii and has a more delicate taste). Its outer colour varies between yellowish-grey and ochre with touches of green. Its taste hints at fresh garlic or shallots. The white Magnatum truffle is eaten raw, grated on pasta or rice.
