Grease a 20cm 8 inch fluted loose bottomed tart tin
Make the Shortcrust Pasty
Place the Flour, Butter, Trex and salt into a food processor and blitz until you have fine breadcrumbs. You can also do this using the rubbing in method with your fingers. But a Food Processor is much quicker.
Add the water. Blitz again until the pastry dough comes together into a ball of smooth, putty like texture.
Wrap the pastry in baking parchment or cling film. Flatten it a little. Place in the fridge for at least 30 mins to rest.
You can prepare the pastry dough the night before. Leave wrapped in clingfilm, overnight in the fridge.
How to Line a Tart Tin with Pastry
Take the pastry out of the fridge and start to roll it out between two large sheets of baking parchment.
Roll from the centre outwards. Turning the dough quarter clockwise as you go along.
Release the sheets of baking parchment as you go along. This will help the dough to roll easily between the sheets of paper.
Roll the pastry out until it is large enough to cover and overlap your tart tin. Any excess will be cut away. These cut offs can be frozen to make an offcut pie another time.
Line your tin with the pastry, allowing plenty to hang over the sides. This is to allow for any shrinkage while it rests in the fridge and during baking.
Place the pastry back into the fridge to rest for at least an hour. Cover the pastry with cling film to help prevent it drying out in the fridge
At this stage you can also prepare the day before and leave in the fridge overnight until required.
How to Blind Bake Pastry
Preheat the oven to 200deg c Fan Assisted.
Take the pastry tart out of the fridge. Prick the base very gently with a fork. Taking care not to cut all the way through.
Line the inside of the pastry with a fresh double layer of industrial cling film. With plenty of overlap. Avoid using supermarket cling film as it will melt.
Fill the case with plenty dried beans, or rice. Fold the clingfilm over the top of the beans to stop them falling out.
Bake on a baking tray in the centre of the oven for 20 mins.
After 20 min. Carefully lift up the beans to see if the base is beginning to look dry. If not, return to the oven for another 5 mins.
Carefully remove the baking beans. Return the pastry to the oven for 5 mins to complete the bake.
Take out of the oven. Leave to cool a little. But not completely.
While the pastry is still warm very carefully trim the flat top edge of the pastry case using a small serrated knife. Use the frame of the tart tin as support. Slicing from the inside out will prevent the pastry edges from breaking.
To make the egg wash. Mix the egg with a little water. No more than ½ a teaspoon. Give it a good whisk. Ensure all the yolk and white are mixed together.
Using a pastry brush, lightly brush the pastry case all over with a thin coating of egg wash. This helps to seal the pastry and prevent a soggy bottom. No one wants a soggy bottom.
Return the pastry case to the oven uncovered. Bake for a further 1 min to dry the egg wash.
Remove from the oven and leave to one side to cool.
Turn the oven down to 175C
Make the Frangipane Filling
Beat the butter and sugar together until light and smooth.
In a small bowl mix together the eggs, Almond Extract and Vanilla Extract. This will ensure all the Almond and Vanilla Flavours disperse throughout the Frangipane Filling.
Add the egg mixture and the flour to the Butter and Sugar. Mix until well combined.
Add the ground Almonds and mix until well combined.
Add the lemon zest. Mix with a spatula
Cover the bottom of the pastry tart with a thin layer of jam.
Add the Almond Frangipane filling to a piping bag. Beginning at the inside edge. Carefully pipe the filling over the top of the jam. Using a small spatula. Evenly spread out the filling.
Bake for 30 – 35 mins until lightly golden and slightly risen. Testing the centre of the tart with a skewer until it comes out clean.
Note. It’s normal to see a few specks of ground almond on your skewer.
Take out of the oven and leave in the tin to cool completely.
Make the icing topping
Mix the icing sugar with the boiled water. One Teaspoon at a time. Until you have a very thick, but slightly runny consistency.
Spread the water icing over the top of the tart. Before the icing sets. Top with toasted flaked almonds.
