Make the vanilla custard
Put the milk, cream, 60 g butter, vanilla paste and caster sugar in a saucepan. Heat over medium, stirring until the sugar dissolves; remove from the heat just before the mixture boils. In a bowl, whisk the egg yolks with the cornflour. Gradually whisk in the hot mixture, then return everything to the saucepan. Cook over medium-high heat, stirring constantly, until it boils and thickens; keep it boiling for 2 minutes while stirring.
Ready to continue when: The custard boils, thickens and completes 2 minutes of boiling while you stir it.
