Preheat oven to 300°F (150°C). Lightly grease a 9’ round cake pan with a removable bottom.
Separate the egg whites from the egg yolks. Set aside
In a deep saucepan heat the milk with the cream cheese until well integrated, and the mixture is homogeneous. Remove from the fire.
Add the cornstarch with a pinch of salt and mix well. Add the egg yolks, and the lemon juice and mix until incorporated
In another bowl beat the egg whites with the sugar, we incorporate it in 3 times, to form stiff peaks.
Add the egg whites little by little, into the cream cheese mixture and mix with encircling movements with a rubber spatula.
Pour the mixture into the prepared pan.
Cook in a double boiler at 300ºF (150°C) for 30 minutes. Then turn to 320°F (160°C) for about 50 minutes more. Keep in mind that all ovens are different.
Let cool before removing.
