Melt butter in 6-quart pan over medium low heat.
To form the roux stir in flour until it forms a paste. Keep cooking the flour/butter combination until it turns a bit golden (about 3-5 minutes). Basically you’re cooking the flour slightly.
Gradually add in the milk whisking it in about ½ cup at a time. Once each addition of milk is incorporated thoroughly and not lumpy, it’s time to add the next. This series of additions will gradually turn the flour / butter paste into a creamy sauce.
Add the stock ½ cup at a time to the cream sauce letting the sauce thicken between additions.
Once all the stock has been added, add the herbs and let simmer for 2-3 minutes.
Add the cubed turkey, carrots, and peas.
Season with sherry (optional), salt, and pepper.
Cook until the Turkey a la King is warmed throughout and the vegetables are lightly cooked.
Serve the Turkey a la King over toast cups or one of the other bread choices.
Enjoy!
