Wash duck breasts, dab dry, make a diamond-shaped incision on the skin side. Season duck breasts with salt and pepper. Place them skin-side down in a cold, ovenproof pan and fry them at high heat for about 5 minutes.
Turn and fry for another 1-2 minutes. Deglaze with 3 tbsp. syrup. Cook in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 12 minutes.
Cut the pomegranate in half and knock the seeds out of the halves with a spoon. Wash and quarter the apples and cut out the cores. Cut apples into narrow slices. Remove the duck breasts from the pan, wrap them in aluminium foil and let them rest in a warm place for about 10 minutes. Set the pan aside.
Bring 500 ml of water to the boil in a pot, season with salt, cinnamon, cardamom and turmeric. Remove from the heat, add oil and stir in couscous. Let couscous swell for about 5 minutes, stirring occasionally.
Steam apple slices with 1 tbsp. syrup in hot frying fat in the pan for 1-2 minutes and salt lightly.
Cut the duck breasts into slices. Arrange couscous with meat and apple slices on a plate and sprinkle pomegranate seeds over it.
