1.  In a sauce pan, whisk the eggs and sugar until well combined. Over medium heat, whisk in the milk and flour. Add the vanilla, cinnamon stick and lemon peel.

2.  Continue whisking the mixture over medium heat until it thickens to a dense cream consistency and no clumps of flour are left, approximately 8 - 10 minutes. Adjust the heat as necessary so that the mixture does not stick to and/or burn on the bottom of the pan.

3.  Once the mixture is cooked, remove the pan from the heat and discard the cinnamon stick and lemon peel. All the cream to cool for at least 30 minutes and then it is ready to use in your favorite desserts.
