Arborio is the stuff that risotto is made of. Its fat, starchy grain makes for silky, rich delicious rice dishes, even for dessert. One of my favorite desserts of all time is rice pudding. The silky richness from the arborio sends it over the top.
Bring milk, sugar, vanilla, and a few dashes of cinnamon to a simmer in a separate saucepan. Add the cooked rice and cook at a simmer over medium-low heat until rice absorbs most of the milk and mixture starts to get thick and silky, about 10 to 15 minutes.
