Place your chilled dough onto a lightly floured surface and roll out into a rough circle. Set your oven to 400f.
Transfer your dough to a tart form and press and trim. Use a fork to create some venting holes.
Cover your tart in parchment paper and then pour in your metal baking beans. These will provide the weight needed to keep your pastry crust from bubbling up.
Bake at 400 for 10 minutes, remove from oven and take weights and parchment off then replace in oven for another 8 minutes.
Mix blueberries, apple, lemon juice, sugar and flour in a bowl.
Top pastry crust with filling and place in oven.
Cook for approximately 30 minutes at 400f.
Allow to cool briefly...
Serve with a generous dollop of whipped cream and enjoy!
