Method:
Sift the flour first to remove any lumps.
Mix together the flour, rind of 2 lemons, juice from 1 lemon, sweetener and 5 egg yolks.
Whisk the egg whites until stiff then fold into the flour mixture.
Transfer into a loaf tin and bake in a 180c oven for appx 30 minutes or until the knife comes out clean.
While that is baking, mix the drizzle ingredients together in a saucepan on a low heat.
Once the cake is done, take out of the oven, pierce with the knife a few times and pour the drizzle over it. Put back in a 100c oven for another 10 minutes.
Remove from the oven and let it cool down a bit before cutting into 8 pieces.
You can serve with a dollop of fat free vanilla yogurt and some fruit.
Enjoy!
