2. Custard cream
INGREDIENTS
250 g milk
The zest of ½ lemon
1 vanilla pod
75 g egg yolk
140 g sugar
30 g rice starch
800 g seasonal fruits for the décor, 400 g per pie
STEPS
Bring the milk with the lemon zests and the vanilla pod to the boil. In a bowl, mix the egg yolks with the sugar and rice starch. Incorporate the boiling milk to the mixture and carry on with the cooking in a bain-marie.
Whisk the cream avoiding lumps (a good cream should not be too thick or lumpy, it should be smooth and unctuous). Finally, fill the baked pastry shell up to two thirds with the custard cream.
Decorate with the fruits and sprinkle with caster sugar.
