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.
Wallago. A catfish of the family of sheatfishes, the Siluridae. It can reach 240 cm (8 ft) in length and is found from Bangladesh to Vietnam and Afghanistan. This aggressive fish is quite feared in some river areas. It is not uncommon to find large fish or frogs in their stomachs.
