Prepare the scallops by cutting each one into 4 thin slices.
Mix together in a bowl the oil, saffron, pepper and salt and cover the scallops with the mixture.
Now prepare an endive salad: cut up the endives and season them with a vinaigrette (cider vinegar, olive oil and salt).
Place the scallops on the endives and sprinkle with caviar before serving.
