Add the corn flour in the cold milk and mix until it has dissolved. Heat the mixture in a saucepan and add the sugar and the vanilla essence or the lemon peel. When the cream is thick, remove from the stove and pour the mixture in a cake tin sprinkled with cold water and let it cool down. When it is cold, empty it in a platter and garnish with fruits in syrup or marmalade or even chocolate syrup.
