Pictured above is a field of mustard we drove by while touring the Côte D'Or in Burgundy in the little village of Querigny-Poisot. Once harvested the crop travels to Dijon, the mustard capital of France.
In talking to our British friend we learned that the expression of cutting the mustard originated in England. In researching this, we learned according to the Guardian,
"WHEN MUSTARD was one of the main crops in East Anglia, it was cut by hand with scythes, in the same way as corn. The crop could grow up to six feet high and this was very arduous work, requiring extremely sharp tools. When blunt they "would not cut the mustard"."
THE MORRIS Dictionary of Word & Phrase Origins (Harper Collins - 1988), relates the phrase to an earlier expression - "the proper mustard", meaning "the genuine article".
“Almost anything is edible with a dab of French mustard on it.” ― Nigel Slater.
Success in real estate or any field of endeavor means that your tools have to be up to date (sharp) and you have to be "the genuine article!" Are you cutting the mustard?
