I must admit that I've never run across a recipe that specified a size of capers ... they just said, x amount of "capers". Thanks to one of the caper links I did recognize the 16-oz bottle of Roland's Capers .... humm ... after digging around in the back of the 'fridge I discovered mine are not "Nonpareil". I was just curious .... doubt that I could taste the difference.
However, I did notice that one site was selling capers in "White Balsamic Vinegar" ... and found that most curious. I've never heard of "white" balsamic (whick looked clear to me) before.
