Sericaia

Preheat oven to 180°C/350ºF.

In a large saucepan place the milk, sugar and flour. Mix everything well with a wire whisk and bring to medium heat. Add the lemon zest and stir until the cream thickens.

Turn off the heat, place the mixture in a bowl and allow to cool until lukewarm.

Meanwhile, in a bowl using an electric mixer, beat the egg whites until stiff and set aside.

Gently beat the egg yolks using a fork and add them into the cream. Stir and then gently fold in the beaten egg whites.

Pour the mixture into a baking dish (roughly 8×8 or 9×9-inch), sprinkle with cinnamon powder (enough to cover completely) and place it into the preheated oven. Bake at 180°C/350ºF for about 20 minutes.

Remove it from the oven, allow to cool and serve.
