Does anyone know what flavor enhancer might be in the above? The restaurant is located in New Brunswick, NJ and makes incredible dishes that are modern updates of tried-and-true favorites. So, the above sauce was served with thin spaghetti and seafood. What was delightful was some distinctive flavor (herb? a mild relative of clove?) that I had never tasted before in this type of sauce. I'm sure I can recreate the sauce if only I know what the magic ingredient is. Does anyone know what this might be?
