So my daughter rises at the crack of noon yesterday, makes herself a coffee and gets worried about the Half and Half because the sell by or use by was a day or so ago. I told her I had just used it and it was fine and to use the old fashioned method of nose and taste buds.
Which led me to think is it these arbitrary dates that cause waste? Not only in our kitchens but at the supermarket level where they are required to throw out food gone past the date even if it is not spoiled. Think of all that food, packaging and effort needed for a foodstore to get rid of it. I grew up in the days where you made your own decisions.
