1: Peel 4 apples and cut into sticks. You can quarter them and cut into smaller pieces if you prefer.
2: Melt 50 g butter in a large frying pan on high heat. When melted, add 50 g caster sugar. Mix and leave the sugar to melt.
3: Add the apples, mix well to coat them in the butter-sugar mixture, then leave to cook just until they are still slightly firm, rather than soft.
4: Pour in 4 tablespoons Calvados (apple liqueur) and mix well.
5: Drain the apples, spread on a baking sheet and leave to cool.
6: Roll out 250 g sweet pastry and line a 7 inch (18 cm) tart tin or ring. Leave the pastry overhanging the edge and put to wait in the fridge for 15 minutes.
7: Meanwhile, prepare the tarte normande filling by whisking together 2 eggs, 10 g vanilla sugar, 30 g caster sugar, 200 ml liquid cream, and 2 tablespoons Calvados (apple liqueur) in a bowl. Preheat the oven to 360°F (180°C).
8: Take the pastry case out of the fridge and trim off the excess (we only do this once the pastry is fully cold so it will shrink less later).
9: Bake the pastry case blind for about 15 minutes.
10: Take it out of the oven and fill with the apple sticks.
11: Pour the filling over.
12: Remove the tart ring if you are using one, then return the tart to the oven for about 20 minutes.
13: When the tart has cooled, finish with a dusting of icing sugar.
Remarks
For an extra flavour boost, lightly caramelize the apples at stage 3 and flambé the Calvados at rstep=4.
