Add 2 cups of whole milk, 3 large strips of orange peel and a cinnamon stick in a saucepan placed over medium heat and as soon as the mixture begins to simmer turn the heat off
While the milk mixture is warming, whisk 4 large egg yolks with 1/2 cup of granulated sugar, 5 teaspoons of cornstarch and a pinch of sea salt in a large bowl
Discard the orange peel and cinnamon stick from the milk mixture
Add a splash of the warm milk mixture into the egg yolks and whisk vigorously
Continue slowly adding a bit of the milk mixture into the egg yolks constantly whisking in between each addition until they are fully combined
Transfer the mixture back into the saucepan and place over medium low heat
Cook while stirring for 1-2 minutes or until the mixture thickens to a custard like consistency and then transfer off of the heat
Optionally, pour the mixture through a mesh strainer to ensure your crema catalana is smooth
Divide the mixture evenly between ramekins, press a sheet of plastic wrap directly onto the top surface of the custard and chill for 4 hours or longer
When ready to serve, carefully remove the plastic wrap and dust the top of the custard with a layer of granulated sugar
Use a chefs torch to brûlée the sugar until golden brown and crisp
Optionally, garnish with whipped cream and fresh orange segments
