Cut off the green of the carrots, so that a small mop of hair remains. Peel the carrots, wash and cook in salted water for about 8 minutes until firm. Then rinse with cold water and drain well. Clean, wash and drain the rocket. For the vinaigrette, squeeze the orange.
Put orange juice, oil, vinegar and mustard in a bowl and mix well. Season to taste with curry, pepper, salt and sugar. Wrap the carrots with Parma ham and arrange with the rocket leaves in portions. Sprinkle everything with the vinaigrette and let it stand for a few minutes. Garnish with orange slices as desired
