Combine rice, 400ml cold water and ½ tsp sea salt in a saucepan, bring to the boil over medium-high heat, stir, then cover with a lid, reduce heat to low and cook until liquid is absorbed (12-15 minutes).
Meanwhile, combine milk, vanilla bean and seeds, cinnamon quill and 90gm sugar in a separate saucepan. Bring to the simmer over medium heat, add rice mixture, stir to combine, then simmer, stirring occasionally, until rice is tender (15-20 minutes).
Meanwhile, combine cornflour and enough cold water to form a thin, smooth paste. Add to rice mixture, stir continuously until mixture thickens (4-5 minutes), remove from heat, cover with a lid and cool to room temperature.
Whisk egg yolks and remaining sugar in a bowl until light and fluffy (2-3 minutes), add to rice mixture and stir continuously over low heat until sauce coats rice (4-5 minutes). Serve warm, scattered with ground cinnamon.
