Hi Kurt,
You can have your own technique, I prefer to put all of them in my mouth and them try to chew (Mission Impossible). But the important thing is that you have eaten all of them beforte the bell stops (Mission Impossible II). Usually they set up the bell in the way that you have enough time, but one year it was too fast and people was complaining for the whole year.
Another tradition, put a ring of pure gold in your cava for luck and don't forget to wear red underwear. If you do so you will have a wonderful year
You can see the Puerta del Sol in the TVE Internacional channel (I hope) or try to go to
www.terra.es and they will tell you where you can see the Puerta del Sol.
HAPPY NEW YEAR!!!!!!!!!!!
