Modern Chocolate Milk

I used to love chocolate milk as a child.  I grew out of it by my teens, and not really care for it since.  I saw some on marked down at M&S, I thought I would re-live the past.  Chocolate milk tastes a lot different now.  I am not sure if it was the modern recipe or just having bought it from an expensive shop.  This recipe has gum to make it thicker and the vanilla to make it smoother.  I remember those I had when I was growing up was very artificially chocolaty!  It is good to taste the difference.
