Want to make your taste buds explode? Sprinkle a pinch of flake salt (or finishing salt) over the frosting after you have spread it onto the bars. Are you wondering why chocolate (and sweet things in general) tastes better with salt? It's because there is a sensor in your taste buds (SGLT1) that is activated by the presence of salt. It recognizes glucose that wasn't being recognized before. In short, it makes sweet things sweeter. Enjoy!
