Preheat your oven to 180'C fan of 200'C conventional
Cut your filo pastry to the size of your tin, make sure to leave the sheets under a damp cloth to prevent them from drying out
Grease the base of your tin with clarified butter and place the first sheet of pastry
Brush the pastry with clarified butter and place another sheet. Repeat this until you have a total of 5 sheets, there is no need to brush the last sheet
Then place 1/3rd of the baklava filling and gently press into an even layer
Drizzle a small amount of clarified butter over the filling and then proceed to place another layer of pastry
Repeat until you have placed 4 sheets of filo. Again there is no need to brush the last layer as the filling will go on top
Now place another 1/3rd of the filling and press into an even layer once again
Repeat this process once more until you have used up all of your filling. You will end up with 3 layers of filling, separated by 4 layers of pastry each
For the last layer use up all your remaining sheets of filo, at least 6-7 for best results
Gently press down to remove any air pockets, and then cut the unbaked baklava into 16 equal pieces
Pour over the remaining clarified butter and allow it to sit for 1-2 minutes to soak in
Bake for 45-50 minutes or until golden brown on top
Immediately pour the syrup over the baklava as soon as it comes out of the oven and allow it to sit for a minimum of 6 hours to infuse. Preferably over night for best results
