Tau suan (sweet mung bean soup) brings back happy memories of my childhood. My late paternal grandmother used to buy it for me as a treat.
The highlight of the dessert is the topping of you tiao (fried dough sticks).
300g mung beans
12 pandan leaves
2½ litres water
140g sweet potato flour
3 Tbs sugar (optional)
4 You Tiao (fried dough sticks, toasted and cut into bite-sized pieces)
1. Soak the mung beans for two hours. Drain off water and rinse.
2. Cut four pandan leaves and place them with the mung beans in a heat-proof bowl.
3. Steam on high heat for 20 to 25 minutes. Check that the mung beans are cooked but not split.
4. Discard the pandan leaves.
5. In the meantime, in a sturdy stainless steel pot, heat the sugar over low heat. Do not stir until the sugar caramelises.
6. Boil the water in a separate pot and add to the caramel. The caramel will crystallise but will melt eventually.
7. Add the remaining pandan leaves into the pot of syrup.
8. Mix the sweet potato flour with 100ml of water to dissolve it. Add the mixture to the syrup.
9. Add the steamed mung beans to the syrup. If you find the mixture not sweet enough, add the sugar.
10. Stir and turn off the heat.
11. Discard the pandan leaves.
12. Serve hot and garnish with You Tiao pieces
