If the Feta cheese is pretty salty, submerge the cheese blocks into a container/large bowl filled with cold water. Leave it for at least 1 hour to desalt.
Preheat the oven at 180C/350F a little higher if not fan assisted.
In a large bowl, with the help of a fork smash the desalted Feta cheese blocks, add 4 eggs, and mix well with half of the yoghurt quantity (400 g), add the turmeric. Turmeric is not only healthy but it gives it a beautiful colour too!
Grease a dish (28 cm/ 20cm roughly) with some of the butter.
Place a layer of pastry containing 3-4 sheets together and then put a layer of the cheese mixture. Repeat this until you finish both mixture and pastry. Best to finish the top layer with pastry. Since the pastry sheets are not going to be the size of the dish, there is no need to cut them but just fold them in.
In the same bowl where the cheese mixture was you can pour the other remainder 400 g yoghurt with the rest of the eggs ( x 3) and whisk well until it is all very well incorporated.
Pour this yoghurt and egg mixture over the last layer of pastry. Scatter the remainder of the butter on top (little knobs) sprinkle a spoon of Demerara sugar on top and place in the oven.
Bake for 45-50 minutes until it is nice' n golden brown on top.
Notes
Serve hot or cold with a little icing sugar on top if you wish and some creme fraiche, double creme, full-fat yoghurt or simply plain as it comes out of the oven. Whichever way you decide to serve it it is absolutely delish!
