Put the egg yolks and sugar in a pan and mix with a wooden spoon.
Add the flour a little at a time, continuing to stir, until the mixture is well blended.
Continue to stir and pour the boiling-hot milk a little at a time, and a little bit of vanilla or lemon rind.
Now add the Buffalo Milk Dulce de Leche and continue to cook on low heat.
