Not much to say on this one, other than you'll be surprised at how delicious it is using the simplest of ingredients.
Another winner from one of my really old cookbooks.
Melt butter in large saucepan; saute celery and mushrooms slowly for about 5 minutes. Stir in 1/3 cup flour, 1 teaspoon salt and pepper; add 1 cup milk and chicken broth gradually (I used the broth from when I cooked the chicken), stirring constantly, till thickened.
Stir in chicken; pour mixture into greased casserole dish.
Sift remaining flour, baking powder and remaining salt together; cut or rub in shortening till mixture is crumbly.
Add milk to make drop batter; drop by spoonfuls on top of hot chicken mixture.
Bake in 425 degree oven about 30 minutes.
This sounds and looks oh so yummy. I've got some turkey, and some turkey broth, celery too.
