Roll out 350 g shortcrust pastry (pâte brisée) to 1/8 inch (3 mm) thick and line a 10-inch (26 cm) tin or ring. Leave the spare pastry overhanging around the edge, then sit the tin on a baking sheet and refrigerate until needed.
Peel 800 g apples and cut lengthways into segments. Melt 50 g butter in a large frying pan on high heat, then add 50 g brown sugar. When the sugar begins to caramelize, add the apple pieces.
8: Cook until starting to colour...
9: ...then tip out onto a baking sheet and leave to cool.
10:
Assembling the tart
Preheat the oven to 410°F (210°C). Trim off the spare pastry around the edge of the tart case.
11: Arrange the apple segments evenly in the tart case. They should not be too crowded.
12: Pour the caramel-apple custard around the apples.
It is best to use a good brown cane sugar, but a beet-based sugar will work instead. You can use sweetcrust pastry (pâte sablée) instead of the shortcrust.
