Chef John's Classic Rice Pudding
If you're nervous about adding the egg yolk to the hot pudding, you can also place the yolk in a bowl, add a small amount of pudding to it, and whisk together. Transfer mixture to the pudding.
Serving ideas: Simply dust top with cinnamon or fresh fruit. Or finish it like a crème brulee: Sprinkle about 1 tablespoon of sugar onto the pudding. Melt the sugar with a chef's torch until crisp and dark brown, 1 to 2 minutes. Allow to cool before serving.
