Prepare the duck extremities well by cooking the wings, thighs, and legs with onion, carrot, scallions, and dried mushrooms. While this is being done, prepare a white sauce with 20g of fat, two tablespoons of wheat flour, and three-quarters of a liter of duck or chicken broth, strained through a fine-mesh sieve. Thicken the mixture with a tablespoon of heavy cream and an egg yolk. Mix in cooked duck or chicken meat, cut into bite-sized pieces and separated from the bones; small broccoli florets and tiny chicken nuggets. Cover with green scallions.
