Syrup
To make the syrup, put the sugar in a saucepan over medium heat and stir nonstop until it melts. After that, gradually add the water and keep stirring so it doesn't caramelize.
Turn off the heat and transfer the syrup to a ring cake pan, spreading it evenly. Set aside.
In a saucepan with the heat still off, place the condensed milk and the corn starch, mix well until combined, then add the vanilla essence, the table cream and the milk, mix very well and bring to a boil.
Over medium heat, stir it nonstop to prevent the cream from sticking to the bottom, until it starts to thicken.
As soon as the cream starts to thicken, lower the heat and keep stirring until it thickens a bit more.
Turn off the heat and transfer all the cream to the pan, give it some light taps so that the cream is flat in the pan.
Place in the fridge for 4 to 6 hours, ideally overnight.
Run a knife along the edges, if needed, to help unmold.
Unmold and serve.
