Vanilla Custard

1 cup milk 
1 cup thickened cream 
1 tsp vanilla extract
4 egg yolks 
1 Tbs cornflour 
1/3 cup caster sugar

Combine milk, cream and vanilla extract in a small saucepan. Place over medium heat. Cook, stirring constantly, for 5 minutes or until hot (do not allow to boil). Remove saucepan from heat. Whisk egg yolks, cornflour and sugar in a heatproof bowl until well combined. Slowly pour hot milk mixture over egg yolk mixture, whisking constantly. Return mixture to saucepan over low heat. Cook, stirring constantly, for 15 - 20 mins or until custard thickens and coats the back of a metal spoon (do not allow custard to boil, as it might curdle). Serve custard warm or cold over stewed fruit, pancakes or crumbles.
