How to cook
Separate 4 tbsp from the milk and dissolve the cornstarch, but make sure that it doesn't have lumps.
Add the yolks and stir again.
In a small saucepan, add the remaining milk, sugar, cinnamon and orange peel and lemon. Put it on the stove and wait for the sugar to melt.
Turn off the heat and leave it for half an hour, so that all the flavors can mix. Strain through a sieve.
Add the yolk mixture to the milk. Place it back onto the hob and wait for it to thicken. Turn it off and leave it to cool completely.
Fill the Vol-au-vent with Catalan Cream and garnish them with fresh fruit.
