Boil the water in a kettle.

In the meantime, mix the starch with a bit of water in a bowl and put aside.

Put the dried prawns and thai chili in a stone bowl (also called lasung) and blend until the ingredients are well combined.

Add the shrimp paste and mix until well combined. Then add some salt according to taste. Put in a small bowl.

Pour a little hot water on the sauce mixture and add the durian. Mix well.

Once the water is boiled, pour it slowly onto the starch until it looks a bit sticky then whisk with a wooden spoon until firm and starchy.

Serve while hot.
