Finely dice 3 orange slices. Roughly dice the nougat, melt in a hot water bath. Stir in orange cubes and grated orange peel. Leave to cool or, if necessary, chill briefly until the mixture is spreadable
Briefly knead 75 g icing sugar and marzipan with hands, cut in half. Roll out each half between 2 layers of foil to form 1 plate (approx. 18 x 24 cm). Place 1 plate (with foil) on a board, remove upper foil. Spread with nougat, let it get a little firmer. Place the 2nd plate on the board with the lower foil, remove the foil. Cool for about 1 hour.
Turn onto a board dusted with icing sugar, remove foil. Cut the board lengthwise into strips (about 3 cm wide). Then cut diagonally into 3 cm wide strips to form rhombuses. Cut the rest of the orange slices into corners. Warm the jam slightly. Decorate the lozenges with 1 blob of jam and 1 orange corner each. Leave to dry. Store in a cool place
