Mix 1 cup of sugar in a bowl until it turns into caramel.
Pour the caramel mixture into a baking dish.
Add 1/2 cup of water and stir until fully dissolved. Remove from heat and set aside.
Heat 1 liter full cream milk, 1 tin evaporated milk, 1/2 cup condensed milk, 1 large spoon vanilla essence, and a pinch of salt together in a saucepan over medium heat.
Add 1 pack of agar-agar (Kijang) to the milk mixture and bring it to a boil until fully dissolved.
Remove from heat and pour the mixture into the baking dish with caramel layer.
Allow to cool at room temperature, then refrigerate for at least 4 hours until set.
Once cooled, unmold the puding caramel carefully.
