Hung yoghurt or curds. The yoghurt is tied into a muslin cloth and hung up overnight. A bowl is placed beneath to catch the liquid which drips out. In the morning the remnant is similar to cream cheese.
Horse mushroom. Edible, and very delicious, but easily mistaken for other less palatable or even poisonous mushrooms.
Galangal. The rhizome of a plant of the ginger family, although it is smaller and more shrivelled. It has more translucent, flesh-coloured skin than the rhizome of ginger. It is peeled and grated or thinly sliced and used in the same way that fresh ginger is used, but has a slightly more complex flavour reminiscent of camphor. Greater galangal resembles a cross between ginger and pepper; lesser galangal is more pungent, with cardamom and eucalyptus flavours, whilst kempferia is the strongest.
