Pour almost all of the milk into a pot, reserving about 1 cup (240 ml). Add the sugar, cinnamon stick, and orange peel to the pot. Heat over medium heat until it starts to boil, then let it simmer for 10 minutes to infuse the flavors. Remove from heat.

In the reserved cup of milk, add the cornstarch and vanilla extract. Mix well until smooth.

Add the cornstarch mixture to the pot. Stir well, then return to the heat. Cook, stirring constantly, until the mixture thickens. Once thickened, pour it into a mold or dish and let it cool completely, preferably overnight.

The next day, cut the set mixture into small squares. Coat each square in flour, then dip in beaten egg. Fry in hot olive oil until golden. While still warm, coat the fried pieces in a mixture of sugar and ground cinnamon. Ready to serve!
