Fried Arrowhead chips (Sagittaria trifolia or Chinese Arrowhead) also known as ngaku is a snack mostly eaten during Chinese New Year. Making these chips is fun and easy, a healthier and cheaper alternative than store-bought chips. They are excellent when deep fried, and taste like potato chips with slight bitterness and a very distinct flavour. Such an easy snack, crispy, nice and gluten-free too.
Tips:
- Use a Mandoline slicer for quick and uniform slices.
- Rinse repeatedly to reduce uneven color at the edge of the chips (brown edges).
- Holding the stems (do not cut off), make slicing with Mandoline slicer much faster and safer.

5 Cut into thin slices with Mandoline slicer.

6 Heat oil to 140°C to 150°C. To test oil temperature without a thermometer, drop a single chip into the oil. The chip should sink then float after 3 seconds or so. If it doesn’t sink, the oil temperature is probably more than 160°C. If oil temperature too hot, the outer layer of chips will burn before it is completely cooked inside.

7 Fried over medium heat until golden. Add few curry leaves in the oil for extra flavor (optional).

8 Remove from heat and drain excess oil on paper towel.

9 Store chips in airtight container only after they’ve cooled completely.
