First let me say, “Darling Clementines” are my favorite.  Always consistent.  I recently purchased a 3lb bag of Darling Clementines expecting my usual sweet tasting fruit.  Unfortunately, that wasn’t true.  They had a very thick skin and membrane which was hard to peel.  The fruit was a darker shade of orange and had a somewhat bitter taste.  Understandably, I was very disappointed and am returning them to the store.  Buying your fruit was never trial and error.  Now I’m not sure.
