Have you ever wondered what capers really are? You know, the sour and salty stuff pretty much like miniature olives usually served with smoked salmon or carpaccio?
I always thought the little pickled thing is a fruit until I came face to face with them in Sicily. They are actually the unripened bud of the flowering plant! They grow wild everywhere in the rocky valley of Scicli. The best thing is, they're free for anyone who is diligent enough to pick though it can be back breaking work!
Reading David's post reminded me of my encounter with this fascinating plant few years ago. If you wish to know how the buds are prepared for eating, he describes it very well here.
