Notes
I recommend that you do not peel the potatoes. The skin helps hold them together which makes serving easier. That’s why we recommend you use new potatoes with a thin skin for a more pleasurable eating experience.
Chop the potatoes and sausage in fairly large pieces that you can easily pick up with your hands, but ideally, they can still be eaten in one bite. Around 1 ½ inches is perfect.
