1 For the dough: Combine the flour, butter, egg and salt and quickly knead until smooth. Cover with plastic wrap and chill for about 30 minutes in the refrigerator.
3 Rinse the chiles and chop finely. Set 1/2 aside. Rinse the leek, trim and cut diagonally into 1 cm (approximately 1/3 inch) thick slices. Rinse the apples, quarter, core and thinly slice. Whisk the eggs, milk, cream, cheese, chile and sesame seeds together and season with salt, pepper and nutmeg. Fill the prepared mold with the mixture and sprinkle with the apples, leek and cashews. Bake until golden brown, around 45-50 minutes. To serve, sprinkle with the reserved chile.
