Pink pepper. This may either be the familiar rose-coloured peppercorn of Piper nigrum, usually preserved in brine or vinegar. It may also refer to the dried berry of a Brazilian plant related to poison ivy. This contains cardanol, which is an irritant to many people and it makes little contribution to cooking anyway.
Shaggy ink cap. A type of fungus which is edible when young. The cap overhangs so that, rather than the more common round cap, the shaggy ink cap has an elongated ovoid shape. It has shaggy scales which, when young, are white but which become darker with age. As it ages it becomes quite unpleasant to eat and eventually dissolves into a puddle of black liquid, giving it its English name.
