Anyway, other than all the food (捞鱼生!!) and the people we get to meet (sometimes really only during Chinese New Year), what I like about Chinese New Year are the assorted plants, flowers, fruits and vegetables that we get to see sometimes only during this period. Arrowhead (慈菇) or Ngaku is one of them. You can only get them during Chinese New Year period. Last year, they were all sold out by the eve of Chinese New Year at my place. Now, arrowhead chips are a must for me to make every year. They are super addictive and are eaten almost as soon as they are fried. :P
If you don't find it troublesome, you can soak them in salt water after slicing them. This was what my friend did. However, you will need a bigger area to dry the sliced arrowhead. The fried chips has a slight salty taste which doesn't need further seasoning with salt.
