THEY are crunchy, tasty and addictive. Once you start crunching on ngaku (arrowhead) crisp, it's hard to stop. These crisps, which look like potato chips, are made from the ngaku, a tuberous vegetable from China which has a woody taste.
Also known as Chinese potato or swamp potato because it grows in water, the ngaku is only available during the Chinese New Year celebration as it is a seasonal vegetable.
