For the fish, prepare a short pastry from the ingredients and let it rest in the refrigerator for about 1 hour. Flatten, cut out with a fish mold and bake over medium heat.
For the glaze, melt the couverture in a bain-marie, stir in orange zest and juice, add Grand Manier. Brush the tail fin with glaze and use a toothpick to set the eye.
