How to cook
Beat the eggs well, pour in the 1 cup sugar and stir until the sugar dissolves.
Pour in the milk and continue stirring. Add in the vanilla as well.
Separately, put the tray with 4 tbsp sugar on the stove. Once the sugar caramelizes, pour in the egg-milk mixture over it and put the tray to bake in a preheated 302°F (150 °C) oven for 45 min.
