1 Wash, dry and chop the parsley. Wash and dry the lemon, finely grate the zest. Mix them in a bowl with the butter and chilli pepper.
2 Remove the crust from the gingerbreads and cut them into thin slices. Spread the gingerbread slices with flavoured butter. Put some duck breast on half of them and cover them with buttered gingerbread.
3 Garnish half of the slices of the second gingerbread with foie gras. Sprinkle crushed hazelnuts on top and cover them with gingerbread. Reconstitute 2 gingerbreads by alternating the flavours.
