I made this:

It turned out quite dense and not at all "light".
I followed the recipe to the letter.
You are advised not to over beat the mixture so I used the paddle attachment in my Kenwood Chef Major and stopped as soon as it was a mixed.
The mixture also curdled.
Any suggestion what might have gone wrong please?
Should I have used the balloon whisk attachment to get more air in the mixture?
How long should I beat it for?
