All you really need is just a couple of potatoes and a cup of flour!You can also make this using sweet potatoes or kabocha squash! It can also be frozen.
This is an easy Italian dish I quickly made when I didn't have much in the house.
Depending on the moisture of the potatoes, this might get sticky, so add some flour or water as needed while mixing to achieve dough the consistency of your earlobe.
