Cream
Start by cutting the wafers in half.
In a small bowl add the milk at room temperature and moisten all the halved wafers with this milk.
Add the wafers to a removable bottom cake pan, arranging them vertically and filling the entire bottom.
In a large pan, add the egg yolks, the sugar, the juice of a lemon, the cornstarch and mix.
Add the milk at room temperature, turn on the heat, set it to medium-low and keep mixing everything very well until it thickens slightly then turn off the heat.
Then, add the white chocolate and stir until the chocolate melts completely.
Add this cream to the cake pan with the wafers and arrange it evenly until flat.
Take it to the fridge and let it chill for at least 3 hours.
After this time has passed, unmold the dessert and decorate with shredded coconut to taste.
Serve.
