Quarter the chicken. Rub with salt and coat thickly with mustard. Put the meat in an ovenproof dish and pepper. Spread the creme fraiche on top.
Bake at 225 ° C in a preheated oven for 45 minutes. Sprinkle the mustard seeds over the chickens 10 minutes before the end of the baking time. Baguette, rice and salad go well with it.
