Cut the raw jack fruit into half and later into medium size long pieces.Remove outer thorny green skin and the center stalk part.

Cut the clean jackfruit into small pieces and put them into water immediately,else they will dis color. Leave it in water for 5 mins. You can observe that the water would be little brownish now. Discard that water.
