First, in a saucepan, mix the sugar with the water and bring to medium heat. Stir until the sugar is completely dissolved.
Next, let it cook until the syrup turns a golden color, being careful not to let it burn. Pour the syrup into a baking dish or a deep plate, spreading it evenly. Set aside.
Now, dissolve the gelatin in hot water, stirring well until it is completely dissolved.
After that, in a blender, place the sweetened condensed milk, heavy cream, milk, and the dissolved gelatin. Blend for 2 to 3 minutes until you get a uniform mixture.
Lastly, pour this pudding mixture over the syrup in the prepared dish.
Finish by placing it in the refrigerator for at least 4 hours or until it is firm.
