Green bean soup was never one of my favourite desserts until I came to UK as this is the only dessert I know how to cook. Fairly simple! Soak the mung beans / green beans for a couple of hours or overnight before placing them into the slow cooker, with a 2 to 1 water to bean ratio. Cook it till soft and mushy. After which, add rock sugar or brown sugar. It is then ready to serve.
Rock Sugar Vs Brown Sugar
If you prefer sweet desserts, then add rock sugar to taste. Brown sugar is for detox.
There are many methods or recipes to cook green bean soup. I prefer it to be plain. You could also add sago or pandan leaves for fragrance. It is entirely up to you.
But do remember that it takes a long time to cook. If you want to eat it for dinner, make sure you cook it in the morning.
