Spherification has been a hot topic in the high tech cooking circles over the last couple of years. Seattle has been the epicenter of some of the experimentation that has been taken place. I've been meaning to experiment with spherification but hadn't made it there yet. Seeing this picture provides some great incentive.
If I left for London now, I think I could make it in time...
Update: This just in.... Here is the cocktail with the pumpkin balls.
