Oliveri harvests these wild porcini mushrooms from the Piedmont region of northern Italy. Their broad tan caps remain firm and intact— as opposed to shriveled and crumbly—resulting in a more robust mushroom flavor. Dried porcini mushrooms are pantry powerhouses that have a stronger, more pronounced flavor than their fresh counterparts. Dehydrating not only preserves porcinis, but it also concentrates and intensifies their characteristic nutty and savory qualities.
