Begin by making the wholemeal shortcrust pastry. While the pastry is resting in the fridge, you can make the Frangipane filling and prepare the rest of the ingredients.
Step 1: Using a food processor, blitz the flour 340 g Spelt Wholemeal flour, vegetable shortening 85 g Vegetable Shortening such as Trex. fridge cold and butter 85 g Butter fridge cold together until you have a breadcrumb consistency or use the rub-in method with your fingertips.
Step 2: Gradually add the water 4-5 tablespoons Cold Water a little at a time (you may not need it all) and bring everything together until you have a smooth, firm dough with a putty texture.
Wrap the pastry dough in clingfilm, flatten it a little, and place it in the fridge for at least 1 hour to rest and firm up.
Preheat the oven to (moderate) 170 deg (Fan assisted oven)
Step 3: Beat the butter 90 g butter at room temperature and sugar 90 g caster sugar together until light, smooth and well combined.
Step 4: Lightly beat the eggs 2 medium eggs with the Almond Extract A few drops of almond extract to distribute the flavours. Then add this to the butter and sugar mixture, along with the ground almonds 90 g ground almonds and flour 45 g white spelt flour . Mix until well combined. Tip: Put the frangipane filling into a large piping bag, as this will make it easy to spread around the wholemeal pastry.
Step 5: Roll out the wholemeal pastry dough between two sheets of baking parchment or on a lightly floured countertop into a 30cm/12-inch disc.
Cover the pastry with half the amount of Marmalade 4 - 6 tablespoons Marmalade, leaving about an inch around the edges. Leave the rest of the Marmalade for glazing.
Step 6: Carefully pipe the Frangipane filling in a circle over the top of the marmalade, leaving around 2 - 3 inches around the edges.
Step 7: Core the apples 3 Dessert Apples medium size and slice them into ¼-inch slices. Sprinkle with a little ground cinnamon 1 teaspoon ground Cinnamon or to taste, if desired.
Step 8: Arrange the slices of apple evenly onto the frangipane filling. Add more cinnamon if you wish.
Step 9: Carefully fold the edges of the pastry over the edge of the Frangipane and apple filling. Seal any folds with your fingers to help prevent the filling from seeping out.
Step 10: Carefully place the rustic apple tart onto a greased baking tray and bake in a moderate oven for 40 - 45 minutes or until baked. The apples should be soft, and the frangipane should be baked in the middle. Test the centre of the tart with a skewer until it comes out clean.
Gently heat the remaining Marmalade, about 2 rounded teaspoons, with 1 teaspoon of water in a small pan. While the Apple and Frangipane Tart is still warm, brush the top of the apples and the pastry with the warmed Marmalade glaze.
Cool before serving with homemade custard or fresh cream. A slice mid afternoon with a cup of tea is delicious.
