Season the foie gras escalopes and pan-fry in a non-stick skillet until golden. Drain on paper towels.
Boil the Sherry vinegar with honey, reduce to a good consistency, then stir in saffron and devil sauce.
Warm the mango fans in the oven. Heat the sauce and add the ginger, green peppercorns, and pink peppercorns.
Per plate, arrange a mango fan, top with a foie gras escalope, and spoon over the spicy sauce.
