Outer Peridium

The outer peridium is the truffle’s skin layer—the textured, often black or pale rind that meets the soil and host-tree world. In ordinary cooking it stays attached to the gleba; each shaving carries a ribbon of peridium and a wider band of marbled flesh. Quality buyers look for an intact peridium without deep cracks that admit rot. Soft or slimy skin means the fruit is failing. Brush dry; never soak. When a recipe says “peel the truffle,” it usually means clean the peridium, not strip it off and discard the luxury you paid for.
