I tried the BBC Good Food magazine's June 2013 cover recipe for my friends birthday. It was delicious very light and not so sweet.
I will post a link to the recipe when it is available on BBC website.
Mr round sandwich tin was old and bruised so I had to use my small square cake tin twice which made the cake look like a giant sandwich.
Icing was made of crème fraiche and yoghurt, I used Sainsbury's brand Greek yoghurt but didn't manage to get the consistency right, it was too thin. Next time I will try it with the Total Greek yoghurt which seems to be much thicker.
