Pat the chicken pieces dry with paper towels, then season thoroughly with salt and freshly ground black pepper.

Heat half the butter in a large, heavy-bottomed pan over medium-high heat. Brown the chicken pieces in batches for even coloring, avoiding overcrowding. Return all pieces to the pan once browned.
03 -
Pour in enough chicken broth to half-submerge the chicken pieces. Cover the pan with a tight-fitting lid and gently simmer for 30 minutes, or until chicken is tender.
04 -
Transfer the cooked chicken to a warm dish and tent loosely with foil to retain heat. Skim any excess fat from the surface of the cooking liquid.
05 -
Combine flour with 2 tablespoons softened butter to form a smooth paste. Stir the paste into the simmering pan juices, whisking constantly until the sauce thickens and becomes velvety.
06 -
Pour the heavy cream into the thickened sauce and return to a gentle boil. Immediately remove from heat once slightly reduced.
07 -
If using egg yolks, beat yolks in a small bowl. Gradually whisk a little of the hot sauce into the yolks to temper, then slowly incorporate the tempered yolks into the sauce off the heat. Do not re-boil to prevent curdling.
08 -
Grate in a pinch of fresh nutmeg and adjust seasoning if needed. Arrange the chicken on a warm serving platter or return to the pan, spooning the sauce generously over the pieces.
