600 g sweet potato (use yellow or orange sweet potatoes or both)
1 bunch of pandan leaves (about 7 stalks) - washed and tied into a knot
60 g ginger - lightly bruised to release juice
Brown sugar - to taste (I used 3 tbsp)
40 g dried longan
5½ cups water
Instructions
Peel and cut the sweet potatoes into small pieces of similar size. Place pandan leaves, ginger, dried longan and water into a medium sized pot and bring to a boil. Once the water boils, add sweet potatoes and simmer for about 7 - 10 minutes or till the potatoes are just cooked through. Do not overcook the sweet potatoes or they will become too soft and disintegrate easily into the soup.
Remove pandan leaves. Sweeten with brown sugar to taste. Ladle into individual bowls and serve immediately.
