Open the vanilla pod in half and collect its seeds.
Boil the milk with the vanilla beans and the pod. Off the heat, add the butter in pieces and mix to melt.
In a bowl, combine the flour, sugar, eggs and yolks.
Remove the vanilla bean from the pan and pour the milk into the dry ingredients. Blend until smooth.
Wait 30 minutes before adding the aromas (rum and orange blossom) to avoid any evaporation.
Place overnight in the fridge. Preheat the oven to 250 ° traditional heat.
Pour the dough into silicone cannelé molds, filling them about 3/4 full.
Bake for 15 minutes at this temperature, then lower to 190 ° and continue cooking for 45/50 minutes approximately depending on your oven. Let cool then unmold.
