Arrange the salad nicely on four plates and spread the Roquefort cheese cut into small cubes on top. Melt the butter in a pan over medium heat and roast the brown sugar and black pepper in it for about a minute. Place the pear wedges in the pan and fry for about two minutes on each side, until they are nicely caramelized and golden brown. Then deglaze with a little balsamic vinegar. Mix in the single cream.
Garnish the salad with the caramelized pear wedges. Finally pour the still warm roasting liquid over it.
