Funghi

Outer Skin

Outer skin is the kitchen phrase for the truffle’s peel when a cook is cleaning or trimming—the same peridium, spoken of as a handling surface rather than an anatomy lesson. Soil clings here; soft brushes and patience remove it without bathing the fungus. Only cut away skin that is damaged or deeply embedded with grit. Healthy outer skin is part of every proper shaving. A specimen whose skin is already collapsing will not improve in the fridge—use it immediately or accept loss.
