Apples with custard (Appeltjes onder een deken)

I decided to participate in another foodblog event. I especially liked this one, because I have an excuse to use this delicious and typical Dutch dessert. The event was started by Raven's blog (which is a very nice blog to check out).
I never had this dessert before I met my boyfriend. It is one of his favorite desserts of his childhood and it is perfect on a cold winter night.
One other advantage of making this is that I once again get to try to make custard. I never seemed able to do it. Maybe it is because of my impatience or just that I never get it right. But I managed this time! Not perfect yet, but I found the method that works for me.

Ingredients (2 persons)

2 apples (I used Elstar)
3-4 tbsp raisins
2 tsp sugar
pinch of cinnamon
Custard:
300 ml milk
200 ml whipping cream
5 egg yolks
60 g sugar
1 tsp cornflour

Preheat the oven to 170 degrees. Peel the apples and remove the core. Mix the raisins with the sugar and cinnamon. Fill the apples with this mixture and put in the oven for 30 minutes.
Meanwhile make the custard. Heat the milk. Whisk the egg yolks with the sugar and cornflour together.
When the milk is at the boil add the mixture to the eggs. Put the mixture in a clean pan and heat on low heat. Keep on stirring until the custard thickens, but do not let it boil.
When the apples are done put them on a plate and pour the custard over the apples.
