While you are cutting the pears, let the oil heat in a large frying pan/skillet.
Fry the pears for 3 minutes a side, and while they are frying whisk the Marsala and honey together in a cup.
When the pears have had their time, add the Marsala-honey mixture and let it bubble up around the pears, and then transfer them, all bronzed and syrupy, to a plate.
Add the walnuts to the dark juices left in the pan and stir-fry them for about a minute until they are themselves darkened in part and sticky all over. Remove them to the plate with the pears and add the Gorgonzola.
