A trade-spec sour built around IP Mushroom Gin's earthy core. Falernum carries the spice, lemon brings the acid, egg white gives the foam crown. Sarsaparilla bitters echo the root-bark register of the mushroom; a walnut-and-Angostura mist over the foam adds an aromatic top note. If you don't have sarsaparilla bitters, sub Angostura.
