First, mix the cornstarch and the tablespoon of water together and reserve

Put all the ingredients in a small pot and bring to a boil. Make sure to stir frequently or it will clump

When the sugar has melted add the cornstarch mixture and stir until the sauce thickens. 30-45 seconds or so . Note that once it cools off it will thicken even more so don’t cook it too much

Let cool and use as needed.
