Preheat the oven to 180 degrees C. (350 Fahrenheit)
Sift the flour in a large bowl.
Cut the cold butter in small cubes, then add it to the flour and rub it in with your fingertips until it resembles breadcrumbs.
Add the icing sugar and milk and knead the dough into a ball.
Cover the bowl with clingfilm and refrigerate for 30 minutes.
Transfer the dough to the working surface and use a rolling pin to roll the dough into an approximately ½cm (¼ inch) thickness.
Carefully roll it around the pin, then line 2 tart tins (mine are 11cm, or 4.33 inch), pressing gently around the edges and the base.
Cover with baking sheet/kitchen foil, then fill the tart tins with ceramic baking beans. This will prevent the dough from shrinking in the oven.
Bake for 15 minutes, then remove the sheet and ceramic baking beans and bake for a further 5 minutes.
Set aside to cool.
To make the filling, add the heavy cream to a bowl, mix in the eggs, sift in the icing sugar and add the vanilla essence. Mix well.
Fill the 2 pastries with the cream mixture, then bake for 10-15 minutes until the cream is set and firm to touch.
Remove from the oven and leave to cool completely.
Decorate with kiwi.
