Pre-heat the oven to 180˚c
Separate the 3 Free Range Eggs
Whisk the Egg Whites until they are at the ‘stiff peaks’ stage (ie stand up on their own – ish)
In a separate bowl, beat the Egg Yolks, Sugar and Yoghurt together until light and creamy
Add the Rape Seed Oil, Lemon Zest and Vanilla Essence
Mix the Flour in carefully and thoroughly
Fold a quarter of the Egg Whites into the Egg Yolk mixture and stir vigorously… Then add the rest of the (three quarters) Egg Whites and fold in very carefully and gently
Pour into a lightly greased Savarin mould (a cake tin in a circle – but any will do, it doesn’t have to have a hole in the centre!) and bake for 30 – 40 minutes or until cooked (it is done when you can put a knife or metal kebab stick into the cake and it is clean when you pull it out)
Leave the cake to cool before turning it out onto a plate. Sieve some Icing Sugar over the cake before slicing to serve
