| 1 | Prepare 350 g  lemon confectioner's custard. When done, cover the custard, stand the pan in cold water and leave to cool. Set aside. |  | 
| 2 | Peel 6 apples and cut into small pieces. |  | 
| 3 | Pour 30 g  clarified butter into a large frying pan on high heat. When hot, add the apples and 2 tablespoons  caster sugar. Sauté the apples until they soften, but without browning. You can flambé them with 3 tablespoons Calvados (apple liqueur) if you wish, but this is not essential. Set aside. |  | 
| 4 | Beat 90 g egg white to the "stiff peak" stage, adding 75 g caster sugar towards the end while still beating, to make the raw meringue mix. |  | 
| 5 | Take a little of the meringue and add this to the lemon custard. Mix in with a soft spatula. |  | 
| 6 | Then add this mixture to the rest of the meringue and fold in gently until evenly mixed and light. Note:Mixing in 2 stages like this helps to combine the two different textures of the meringue and confectioner's custard. |  | 
| 7 | Add the apple pieces and mix again gently. Preheat the oven to 390°F (200°C). |  | 
| 8 | Put the mixture into a buttered gratin dish and bake for about 10 minutes. |  | 
| 9 | After 5 minutes, sprinkle the top with caster sugar and change your oven setting to "grill" (broiler) to brown the top (if your grill is separate, leave the dish in the oven for a couple of minutes longer, then brown briefly under the grill). |  |
