Add the ground almonds to a mixing bowl. Sift in the flour and icing sugar. Stir together.
150 g plain flour, 50 g icing sugar, 20 g ground almonds
Add the almond extract and stir together.Note: This is optional. The ground almonds add a beautiful crumbly texture to the pastry but not a lot of flavour so we add almond extract to add more almond flavour. 1 tsp almond extract
Add the vegetable shortening and margarine to the bowl and rub briefly with your hands until the mixture resembles breadcrumbs.
50 g vegetable shortening, 50 g dairy free margarine
Add the cold water and bring the dough together into a smooth ball. If it is not coming together then add another tsp of water. Don’t overwork the dough, handle it lightly until it just comes together.
1 tbsp water
Wrap the pastry or cover the bowl and place it in the fridge for 1 hour to fully chill. Don't be tempted to skip this step.
Preheat the oven to 170°C fan (190°C conventional / 375°F / gas mark 5) and set aside six 10cm / 4" non-stick individual tart baking tins.
Lightly flour a smooth surface and rolling pin.
Roll the pastry out nice and thinly (around 1/4 cm or 1/8") and place it over each of the tartlet dishes. Gently press the pastry into the shape of the dish and then trim off any pastry that is overhanging the top. Re-roll the pastry as necessary and repeat the process with the other tart tins.Tip: Use a small ball of pastry wrapped in eco cling film to press the pastry down, to avoid tearing the dough. Prick the base and sides of each pastry case with a fork and bake for 12 minutes, until the pastry is just starting to colour and is cooked through.
Once the pastry cases are baked, set them aside to cool completely on a wire rack and make your jam.
