4 eggs, separated
100g granulated sugar
45mll flour
400g greek yoghurt
grated zest and juice of 1 lemon
a pinch of salt
Preheat your oven to 180℃ and spray a 22cm loose-bottom cake tin with cooking spray.
Add the egg whites to the bowl of a stand mixer fitted with the whisk attachment.
Whisk on a medium-low speed until the whites are frothy.
Increase the speed to medium-high and whisk until soft peaks form.
Spoon the whites into another bowl and set aside.
Add the yolks and sugar to the mixer’s bowl and whisk on a high speed until pale and fluffy – about 3 minutes.
Turn the mixer to medium speed and gradually add the flour, yoghurt, lemon zest, juice and salt.
Continue whisking until the ingredients are fully incorporated.
Take the bowl from the mixer and add half the egg whites. Gently fold through with a spatula.
Add the rest of the whites and fold in.
Scrape the bottom and sides of the bowl so that you end up with a very evenly mixed batter.
Spoon the batter in to the prepared cake tin and smooth the top.
Bake for 55 minutes – if the cake becomes too brown place a piece of aluminium foil loosely over it while baking.
Take the cake from the oven and cool on a wire rack.
