Instructions
Shortcrust pastry:
With a mixer
- Sift the flour into a bowl.
- Place the butter, salt and sugar in a mixer fitted with a plastic blade; add the egg yolk and milk. Blend until smooth.
- Add the flour.
- Blend, and as soon as the dough forms a ball, stop the blender.
- Wrap the dough in cling film and leave to rest in the fridge for at least 2 hours.
By hand
- Cut the butter into small pieces in a bowl. Crush the pieces with a wooden spatula to soften them, stirring quickly.
- In a bowl, mix together the milk, salt and sugar, then drizzle over the butter, stirring regularly.
- Add the egg yolk.
- Sift the flour over a bowl.
- Stir it into the butter several times.
- Knead the dough very quickly.
- Place the dough on your floured work surface. Using the palm of your hand, flatten the dough by pushing it in front of you. Gather it into a ball and repeat the same operation. Shape the dough into a ball, then flatten it slightly. Wrap it in cling film.
- Leave to rest in the fridge for at least 2 hours.
- Preheat your oven to 180°C (gas mark 6).
- Roll out the shortcrust pastry in a pastry ring 24 cm in diameter and 3 cm high.
- Prick with a fork and leave to rest in the fridge for 30 minutes.
- Then cover the pastry with a sheet of greaseproof paper and garnish with dried beans. Place in the oven and cook for 20 minutes, then remove the paper and beans. Return to the oven for a further 10 minutes.
Tips and advice: You can either use the dough immediately after resting, keep it in the fridge for 2 days, or freeze it in tightly-wrapped portions. Before using, let it defrost slowly in the fridge. Spread the thawed dough but do not rework it, as this will cause it to lose its melt-in-the-mouth texture.
Spoon biscuits:
- Preheat your oven to 230°C (gas mark 7-8).
- Sift together the flour and cornflour.
- Whisk the egg whites with the sugar until stiff.
- Pour the yolks into the egg whites; mix gently for a few seconds.
- Fold in the flour and cornflour, lifting the mixture with a spatula.
- Spread the sponge cake on a baking tray lined with silicone paper, then place in the oven and bake for around 5 minutes. Remove from the oven and cool on a wire rack.
- Leave to dry at room temperature, then blend very finely.
Cinnamon sugar:
- Mix the ingredients together.
Assembly and finishing:
- Preheat your fan oven to 160°C (th. 5).
- Sprinkle the pre-baked tart base with approximately 50 g of dried biscuit spoon powder.
- Cut the quetsches in half and remove the stone; arrange them upright on the tart base, holding them as tightly as possible.
- Sprinkle generously with cinnamon sugar, place in the oven and bake for 30 to 40 minutes.
- Leave to cool to room temperature.
- Brush the apricot jam or apple jelly around the edge of the tart, then cover completely with cinnamon sugar.
- Place the tart on a serving dish and keep at room temperature.
- Before serving, sprinkle the tart with cinnamon sugar.
