Ingredients
- 4 egg yolks
- 0.7 oz cornstarch
- 0.7 oz all-purpose flour
- 3.5 oz sugar
- 2 cups whole milk
- lemon zest
- puff pastry (2 pre-baked rectangles)
- 10 ladyfingers
- to taste alchermes
- powdered sugar
Tools
- Tray
- Saucepan
- Bowl
- Hand whisk
Preparation
Heat approximately 1 1/4 cups of milk in a saucepan along with the peel of half a lemon, without bringing it to a boil.
Meanwhile, mix the egg yolks with the sugar in a bowl, using a whisk. Add the flour and cornstarch sifted, alternating with the remaining 3/4 cup of milk.
Once you have obtained a smooth and lump-free mixture, pour it into the saucepan and stir.
Cook for 6-8 minutes over low heat, stirring with a wooden spoon.
When the cream has thickened, pour it into a glass container, cover with contact plastic wrap, and let cool well.
Take a tray (or the container you want to serve the dessert in) and place one of the puff pastries on it.
Cover with half of the cream and level.
Dip the ladyfingers in the alchermes and arrange them over the cream.
Now add the other half of the cream and cover with the second puff pastry, without pressing.
Dust the surface with powdered sugar, and your quick diplomatic cake is ready!
I recommend letting it rest in the refrigerator for at least an hour, so it cools well and the layers settle.
Serve the diplomatic cake by cutting it into squares, it is also excellent as a dessert at the end of the meal.
Tips and Variations
You can also fill it with diplomatic cream (here the recipe).
Instead of ladyfingers, you can use a rectangle of sponge cake.
If you want to bake the puff pastry yourself, get 2 rolls of fresh puff pastry, dust the surface with powdered sugar, pierce with a fork and put in a ventilated oven at 350°F until golden (about 12-15 minutes).
You can dilute the alchermes with a little water or orange juice if you want a less alcoholic dessert.
Store leftover portions in the refrigerator, in a closed container.
