Preheat the oven to 150°C (thermostat 5). In a saucepan, warm the milk with the sugar. Split the vanilla pod in half, extract the seeds, then add them to the milk along with the two halves of the pod.
Beat the 6 eggs.
In the flan mold, prepare a caramel: place the sugar cubes in the mold and add a small amount of water. When the caramel is ready (be careful not to let it brown excessively), tilt the mold to spread it evenly over the entire surface.
When the milk begins to boil, gradually add it to the eggs while stirring continuously.
Then pour the mixture into the mold.
Bake in the oven in a water bath for about 45 minutes.
Check whether it is cooked by inserting the tip of a knife: it should come out clean.
