1) In a medium bowl, combine the oats and milk. Cover and let soak in the refrigerator overnight.
2) Transfer the oat mixture to a heavy-bottomed medium saucepan. Add the salt and cinnamon sticks and bring to a boil over high heat. Lower the heat to maintain a gentle simmer and cook, uncovered, stirring frequently, until softened, about 10 mins. Stir in the vanilla, currants, and sugar; and simmer for 5 mins more. Remove the cinnamon sticks and serve plain or with your topping of choice.
