Using broth made from a turkey carcass instead of chicken broth will enhance the turkey flavor considerably
Tempering the cream and egg yolk mixture prevents curdling - always add hot soup to the cream first
The additional broth added with the turkey helps create the perfect consistency and prevents the soup from being too thick
Dry sherry can be substituted with white wine or omitted entirely if preferred
This soup can be made ahead but add the cream mixture just before serving to prevent separation
Leftover soup will thicken in the refrigerator - thin with additional broth when reheating
Fresh herbs can be substituted for dried herbs using a 3:1 ratio
