Execution
Follow the master commands
Put the milk, cream, cinnamon stick and all the citrus zest in a saucepan set over a medium heat. Cook, stirring often, until the milk is just steaming but not boiling, about 3-5 mins. Remove from the heat, cover with a plate and leave to infuse for at least 30 mins.
When the cream mixture has infused, whisk the egg yolks, sugar and cornflour together in a separate bowl for 3-5 mins, or until light and pale in colour. Pour the infused milk through a sieve into the egg mixture, whisking continuously. Return the mixture to the saucepan.
