How to make
Lay out the puff pastry, cut it into 1/2″ (1 cm) thick strips lengthwise. Wrap each strip around an aluminum cone mold. Put baking paper in an oven dish and arrange the cones in it.
Smear them with a beaten egg yolk and put in a preheated 390°F (200 °C) oven for 10 min. Take them out, remove the cone molds and let the cones cool.
For the cream, put 3 1/3 cups (800 ml) of the milk with the sugar and butter in a pot. Put it on the stove to boil.
Beat the 3 eggs, 3 yolks and remaining milk with the flour. Pour them into the milk in a thin trickle, while stirring nonstop. Stir until you get a thick cream. Flavor with the vanilla and take off the stove.
Let the cream cool a little bit, then fill the cones with it. If desired, sprinkle crumbled walnuts.
