2: Melt 40 g butter (clarified if possible) in a frying pan over high heat, add apple quarters. Cook 2 or 3 minutes, then sprinkle with 3 tablespoons caster sugar and cook a few more minutes until well caramelised. Set aside.
3: Slice 300 g stewed apple (compote) fairly thinly (1/2 cm or 0.4 inch thick) and remove crust. Cut into rectangles same height as your mould, and triangles for top and bottom. Try the brioches pieces in the mould to check for fit: the rectangles should overlap slightly.
4: Turn on the grill. Melt 3 tablespoons clarified butter. Put all the brioche pieces on a grill pan or thick baking sheet.
5: Using a brush, coat each slice of brioche with melted butter, then sprinkle with some caster sugar.
6: Put under the grill.
7: Supervise carefully, remove brioche pieces as soon as they are golden brown. Set aside.
8: Brush the mould with melted butter, then put in 1 tablespoon caster sugar and spread it around evenly by shaking and turning. We do this to make turning out easier after cooking. Preheat oven to 392°F (200°C).
9: Line the mould with brioche pieces, toasted side against the mould, overlapping the rectangles slightly.
10: Add stewed apples to about ¼ depth of mould.
11: Then a layer of caramelized apples .
12: Then a second stewed apples layer, and finally a layer of brioche .
13: Put in the oven for about 30 minutes.
14: Allow to cool a for a while before turning out.
