Chestnuts. To peel chestnuts the hard outer skins need to be slit and then the chestnuts roasted or grilled until these skins crack. They can then be peeled off and the chestnuts boiled for ten minutes, after which it should be relatively easy to rub off the inner, papery brown skin.
Brick Cap mushroom. This is an edible mushroom, often eaten in the United States and Japan, which is easily confused with poisonous varieties, so special care should be taken.
