How to make
Soak the prunes in the rum for 24 hours, stirring them periodically.
Beat the eggs, sugar and vanillas to a fluffy cream and add the sifted flour and starch, while stirring nonstop.
Then pour the milk in a thin trickle, again while stirring, until the mixture homogenizes.
Strain the prunes and roll them in 1 tbsp flour.
