1liter (32oz) fresh milk
140 g (¾ cup) granulated sugar
50 g (1/3 cup) cornstarch
Zest of 1 lemon
1 vanilla pod
Custard is perfect for garnishing fruit tarts, choux pastry preparations and many other cakes.
Take the vanilla pod, flatten it on a smooth surface, cut it in half lengthwise, and scrape the seeds using a knife. Pour the milk into a large pan and add the seeds and the two halves of the vanilla pod, which will be removed later.
Put the egg yolks in a bowl and add the sugar, stirring with a whisk. When the mixture is creamy, add the cornstarch, continuing to stir to remove any lumps.
At the first boil, add a few ladles of milk to the mixture and stir. Add the lemon zest and all the remaining milk. Pour the cream back into the pan and cook for a few minutes on the simmer.
Cool the custard quickly on a smooth surface or in a bowl while stirring constantly.
