Like making a souffle, it's a fair bit of work to get the preparation right, and then it's all too easy to lose that precious lightness and end up with a disappointing flatness. But in both cases a successful result is delicious, luxurious and oooohhh so worth the effort!
At this stage I think the key for me is just more practice. The technique is remarkably different from the way I normally spin and I need to develop a light hand. I'm told the key is to relax! Relaxing never has been one of my great strengths--and concentrating on relaxing is one of those tantalising oxymorons! But I'm going to have another go today.
