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.
Potash. Araising agent used to make a baked mixture light. Baking powder consists of bicarbonate of soda (US: baking soda) and cream of tartar which, if mixed with flour or starch, assists pastry and cake doughs to rise, as when it meets moisture it produces carbon dioxide which aerates and lightens the dough.
Lingonberry or cowberry. Red whortleberry. It is similar to a cranberry.
