Cut the thin slices and put a little oil, salt and sugar in the small bowl and mix. Just a little bit, because the taste of the taro itself is very sweet.
Preheat the oven 300F/150C and brush a little oil on the tin foil. Spread the slap slices, try not to overlap
Bake for about 30 minutes (depending on the size of the oven), it's hard to become crispy!
