I have been looking for two years for a substitute for Knorr-Swiss packet Newberg Sauce. It has been discontinued. My sister-in-law has an answer. Make a roux ( flour and butter) add cream, sherry, paprika and a jar of Kraft Old English cheese (no cheating). The jar looks like nasty stuff but that is the recipe. This version is at least 80 years old and is a Maine staple.
