In a pan at medium heat, place the milk and the water. Then incorporate to the mix the cornstarch and the Le Zuc. Stir all the ingredients until they dissolve. Wait until the mixture boils and thickens for approximately one minute. Beat the eggs and incorporate them only to one half of a cup of the mixture in the pan. Then place the egg mixture into the pan with the rest of the preparation and stir at low heat until it thickens. Make sure to stir to avoid lumps in the mixture. Finally, remove the pan from the heat and incorporate the vanilla. Serve in the recipient of your preference, let it cool and sprinkle with a little bit of cinnamon.
