In a large deep pan add the milk and a pinch of salt and bring to a boil.
When the milk begins to boil, gradually add the cornflour, mixing constantly with a whisk to avoid clumps from forming.
Boil the mixture for 10 minutes, then turn the heat off and set aside to cool.
Meanwhile, in a bowl, mix the cottage cheese with 100g (3½ oz) of the sheep’s milk cheese, using the back of a wooden spoon to break apart the clumps of cheese.
Crack the eggs and separate the yolks from the egg whites. Add the yolks to the cheese mixture and combine well until homogenous.
Beat the egg whites with a pinch of salt until the mixture foams. Set aside.
Preheat the oven to 190° C/ 375° F and prepare a 20x30 cm (8x12 inches) and line it with parchment paper.
Mix the warm milk and cornflour mixture with the cheese until well combined. Finally, add in the egg whites, mixing carefully with a spoon with upward movements.
Pour the mixture into the baking dis hand level it with a spoon. You can add an extra 50 grams (1 ¼ oz) of sheep’s milk cheese , grating it over the top.
Place in the oven and bake for 35-40 minutes until the top turns golden-brown.
Serve warm with a generous dollop of sour cream on the side.
Enjoy!
