For the saffron apples topped with blue cheese, first cut the apple into wedges and remove the core.
In a saucepan, heat the sugar and let it caramelize until light brown. Deglaze with apple juice and sweet wine. Add saffron and dissolve sugar while stirring repeatedly. Season with pepper, add apple slices and let them steep in the broth for about 3 minutes.
Divide the apple slices between 2 ovenproof plates, drizzle the juice over them and place the cheese on top. Put the plates in the oven and bake the saffron apples with blue cheese briefly at 200 °C until the cheese has melted nicely.
