Butterscotch Pudding - unsalted butter

Method

• In a medium saucepan over medium heat, melt the butter. Add the brown sugar and reduce heat to medium-low. Let it heat and bubble for 1 to 2 minutes, stirring frequently. Don't let it smoke or burn, which brown sugar is always very eager to do. Reduce heat to low. Add salt and cornstarch, stirring until combined - it's going to look like a thick paste. Switch to a whisk and add the milk in a thin drizzle, whisking the whole time, so that no lumps firm. Once all of the milk is added, you can switch back to a spoon. Cook over low to medium-low, stirring frequently, until the mixture comes to a gentle simmer. Let it simmer for a full minute, stirring, it should clearly thicken at this stage, although it will finish thickening in the fridge. Off the heat, stir in the vanilla extract. Divide into glasses or pudding cups and let chill in fridge for 1 to 2 hours, until set.
