My Family loves this dish they request it often.
Stew a whole chicken with 1 diced onion and 3 ribs of celery diced. until it begins to fall apart.
Remove chicken from broth and allow to cool.
Remove the chicken from the bones discarding bones and skin (of course) add the chicken back to the broth.
Continue to boil the broth until it has reduced to barely cover the chicken.
Place the chicken and broth into a very large baking pan. I use an 11x15x2 or 2 casserole dishes.
Heat oven to375*
Make the biscuit mix and spoon over the top (doesn't have to cover every square inch, as the biscuits will spread out somewhat, but I usually scoop a little out flatten it with my hands, place it on top )
Whisk these together
1/2tsp. baking soda
1-1/3cups buttermilk (just add 1tbl white vinegar to a measuring cup and fill to the 1-1/3cup mark with milk and allow to stand for 15 minutes. you have buttermilk)
2/3cup melted margarine
Just barely mix to moisten all the flour. place over chicken
Bake at 375* until lightly brown. Allow to stand about 15 minutes. This steams and softens the biscuit.
