In addition to the peanut butter and jelly sandwiches, here is another item I ate for the first time in years:
A Tootsie Roll! I really liked these as a child and the last one I ate before the above was sometime between 2005 and 2010. Have my taste buds changed to dislike Tootsie Rolls? Not at all! The flavour is as delicious to me now as it was many years ago. You can by these from some Tesco stores here.
