Peel the skin of each arrowhead but leave each stalk intact.
Using a slicer or mandolin, hold each arrowhead by the stalk and carefully shred the arrowhead to thin circular chips. If using electronic slicer, there is no need to retain the stalk.
Pat dry sliced arrowhead with paper towels. Spread them out on large plates and air dry for about 3hrs.
Heat oil for deep frying in a pan.
Test temperature by inserting a bamboo chopstick in the hot oil. If oil is ready, you should see small bubbles gathering around the chopstick.
Deep fry the arrowhead chips, in small batches, add 5pcs of curry leaves into the oil and fry together.
Take out the chips when theyturn light golden brown.Leave the curry leaves in the oil.
Drain fried arrowhead chips on paper towels or tempura paper.
Season with taste with salt. When arrowhead chips are cooled, store them in air-tight containers.
