Scald milk, stirring, over medium-low heat

Stir in the orzo

Cook, stirring frequently and adjusting heat to prevent milk from boiling over and scorching, until the mixture is very thick and orzo is tender to the bite, 20 to 25 minutes

Remove from heat and stir in the vanilla

Pour mixture into a large bowl or four individual custard cups

Cool slightly

Serve warm or at room temperature for dessert or breakfast and top with chilled heavy cream if desired
