YIELD: 12 cannoncini
For the custard cream (crema pasticcera):
3 egg yolks
3 tablespoons (30 gr) of all-purpose flour
1/2 cup (100 gr) of sugar
1 teaspoon of vanilla extract
8 oz (235 ml) of milk
For the cannoncini:
1 sheet of puff pastry, defrosted (about 8 oz, 225 gr)
1/4 cup (50 gr) of sugar
1 egg (for egg wash)
powdered sugar to decorate
Start by preparing the custard cream (crema pasticcera):
Warm up the milk until hot (not boiling).
In a medium sized pan, whisk the egg yolks with the sugar, vanilla extract and flour, until light and fluffy.
Add the milk some at a time while whisking, making sure there are no lumps.
Place the pan over medium heat and stir continuously until it reaches a slow boil. The cream will thicken, so be careful not to let it stick to the bottom. Lower the flame and cook for a couple of more minutes, until you reach the desire thickness.
Pour the cream in a glass bowl, cover with plastic wrap and let it cool down. Refrigerate for at least one hour.
For the pastry horns:
Preheat the oven to 400°F (200°C).
Sprinkle some sugar on the counter and on top of the puff pastry and roll it out to a rectangle about 9 by 12 inches.
Cut into 12 stripes (about 1 inch thick). Easy way to do it: cut the pastry in three parts, and then each part into four strips.
Roll each strip onto a horn mold (conical in shape). The pastry has to overlap (about half of the length).
Place on a baking sheet lined with parchment paper with seem (end of the strip) side down.
Beat one egg with one tablespoon of water. Brush lightly each pastry cone with the egg wash.
Make sure you keep the egg wash away from the mold. It will make it harder to remove the pastry horn from the mold once baked.
Bake at 400°F (200°C) for about 15-20 minutes until golden on top.
Let them cool down for a couple of minutes and gently remove from the mold.
If the pastry sticks to the mold, you can press in the mold a little (to make the circumference smaller) and very gently turn it inside the pastry until it comes off.
Before serving, fill with the cream.
Sprinkle with powdered sugar if you like and enjoy!
