Method:

First thing first, slice your apples thinly, about 3 to 5 mm thick. Then prepare your pastry, with a knife I draw a rectangle close to the edges of my pastry to create a border. Then I lay my apples in rows until they have completely covered my puff pastry.  At that point, sprinkle your apples with a generous amount of muscovado sugar, and add nuggets of butter on top of your apples. To add a bit of colour I also added a few blueberries, you could use blackberries also at this time of year. Pop your tart in the oven, for 20 minutes or until the edges and bottom of the tart are cooked. This is a dessert that can be eaten warm or cold, the choice is yours.  

Bon appetit!
