Melt the nougat in a hot water bath. In the meantime, finely dice 3 candied orange slices. Stir into the nougat mixture together with the orange fruit. Let it cool down a bit. Sift the icing sugar into the marzipan and knead.
Halve the mixture and roll out to two rectangles (approx. 24 x 18 cm) and cut straight. Put cling film on a board and dust with icing sugar. Place a marzipan base on top and spread evenly with nougat mixture. Let the nougat mixture rise slightly, cover with the second marzipan base and put in a cool place for about 1 hour. Turn the platter over onto a board dusted with icing sugar, remove the foil and cut the platter lengthwise into strips about 3 cm wide. Then cut diagonally into 3 cm wide strips as well, so that even rhombuses are created. Cut the remaining orange slices into fine corners. Warm the jam slightly and decorate the lozenges with a blob of jam and an orange corner. Leave to dry.
