1. Preheat the grill (broiler) to medium. Skin and trim the duck breasts to remove any excess fat. Score the flesh in diagonal lines and pound it with a meat mallet or a covered rolling pin until it is 1.5 cm/ 3/4 inch thick.

2. Place the duck breasts in a shallow dish. Mix together the vinegar, brandy and honey in a small bowl and spoon over the duck. Cover and leave-to chill for about 1 hour.

3. Drain the duck, reserving the marinade, and place on the grill (broiler) rack. Season and brush with oil. Cook for 10 minutes, turn over, season and brush with oil again. Cook for 8-10 minutes until the meat is cooked through.

4. For the sauce, reserve 60 g/2 oz raspberries and place the rest in a pan. Add the reserved marinade and the wine. Bring to the boil and simmer for 5 minutes until slightly reduced.

5. Strain the sauce through a sieve, pressing the raspberries with the back of a spoon. Return the liquid to the pan and add the cornflour (cornstarch) paste. Heat through, stirring, until thickened. Add the reserved raspberries and season.

6. Slice the duck breast and arrange fanned out on warm serving plates, alternating with slices of kiwi fruit. Spoon over the sauce and serve.
