Start by making the filling so that it can cool whilst preparing the rest .
To make the filling ; Place the cubed butter into a small saucepan and melt over a gentle heat . Once butter has melted add the sugar , eggs and the juice of 3 lemons to the melted butter in the saucepan and keep cooking over a gentle heat until mixture becomes thick , stirring continuously , once thickened and ready , remove from the heat and pour into a heatproof jug or bowl and leave to cool completely .
Preheat your oven to 180°C then grease the inners holes of a cup cake tray / muffin tray , then cut some long thin strips of baking paper and place two strips , per tray hold , cross ways inside the cake tray holes . This will assist you with the removal of the tarts from the cake holes once cooked . Set aside till needed .
To make the pastry ; sift the flour into a large bowl and add the sugar and mix to combine , now add the cubed butter into the flour mix , and either , blend together using a blender or use your fingertips to rub together the butter and flour , to form a breadcrumb type mixture .
Whisk the egg Yolks then add the Cold water and whisk again to combine .
Make a well in the middle of the flour crumb mix and pour the egg mixture into the flour crumbs mix and mix together to form a dough , then divide the dough into 12 equal portions and roll each portion into a dough ball .
Now take the prepared rolled dough balls and , doing one at a time , carefully flatten the dough ball into the palm of your hand to form a disc shape , then press the prepared dough disc into and down one of the holes in the prepared cake tin to form the pastry dough shell . Repeat with all remaining dough balls .
Once cake tins are filled with the dough shells , place the tray into the preheated oven and bake for 10-12 minutes or until lightly golden . Remove from heat so you can now fill them and proceed .
Once removed after the first round of cooking , take the prepared cooled lemon filling and carefully and evenly spoon the lemon mixture into all the cooked prepared pastry shells and spread with the back of the spoon to cover pastry shells evenly .
Place prepared lemon filled pastries back into the Preheated oven and bake for a further 10-12 minutes or or until golden brown . Once cooked remove from the heat and let cool for at least 5 minutes in the tray . Once cooled a little , using the baking paper strips to help , carefully lift the tarts out from the cake tin tray and place on wire rack to cool completely .
Once cooled , place on a serving plate , top with fruit and whipped cream if desired or toppings of your choice , or just as good on their own . Enjoy . :-) .
