Ingredients:
4 tbsp cornstarch
5 cup whole milk
1 slice lemon zest
1 slice orange zest
1 cinnamon stick
1 cup sugar
10 egg yolks
Additional sugar (Sugar in the Raw) to caramelize the top of each custard portion
Procedure:
Dissolve the cornstarch in an equal amount of cold water and reserve. Place the milk, lemon and orange peels in addition to the cinnamon stick in a sauce pot and gradually bring to a simmer.
Whisk the sugar into the egg yolks and mix until the sugar is completely incorporated. Gradually stir in the dissolved cornstarch along with approximately a quarter of the milk.
Gradually stir the egg yolk mixture into the rest of the milk off of the fire. Return the custard mixture back to the fire, on medium-low heat, stirring continuously.
When the mixture begins to thicken to the point where it coats the back of the spoon, remove from the heat. Immediately strain the custard through a sieve into a bowl set in an ice bath.
Stir the mixture over the ice for a few minutes before ladling into custard dishes and chill in the refrigerator.
To serve: sprinkle each portion with a thin layer of sugar on top. Take a blow torch to caramelize the surface. Garnish with berries or some other fruit to serve.
