The bottoni pasta with truffles are a greedy pasta format where the filling prevails both in taste and in quantity.
I recommend pairing a plate of buttons with a medium-bodied red wine:
Sangiovese DOC or Aglianico DOC, Italy
Grand Cru Morges AOC La Cote or Blauburgunder DOC Zurich, Switzerland
Bordeaux AOC or Medoc AOC Cru, France
