Calabro mushroom" likely refers to Porcini mushrooms from the Calabria region of Italy, which are a prized delicacy known for their intense flavor and versatility. These mushrooms, particularly those from the Sila mountains, are used fresh in dishes like pasta or carpaccio, preserved in oil, dried, or even used to create a unique liqueur. The term can also refer to other regional mushrooms preserved in oil, such as Porcinello or Muschio mushrooms.
