If you are wanting to make this a fermented sourdough chicken pot pie, start the biscuits the night before.
Chop up cold butter into chunks and add to a large bowl.
Add flour to the butter.
Cut butter into flour using a fork, food processor, or with your hands,
Add 1 cup of sourdough starter.
Add sugar and stir until nicely incorporated.
Add the milk or buttermilk.
Place a clean tea towel over bowl and allow to sit at room temperature at least 8-24 hours.
The next day, add diced potatoes, carrots, onions, garlic, and butter to a cast iron skillet at sauté on medium low heat for 10 minutes until they start to soften.
Sprinkle flour over the sautéed vegetables and butter. Stir and cook a few minutes.
Add broth, dried parsley, garlic powder, and onion powder. Mix and cover with lid. Allow to cook for 10 minutes.
To the skillet, add peas, pre-cooked chicken, and heavy cream.
While the filling continues to cook, finish making the biscuits by adding baking soda, baking powder, and salt to the fermented dough.
Mix everything together well. I like to use my fingers.
Roll out biscuits onto a lightly floured surface and cut with biscuit cutter.
Top the filling with sourdough biscuits and place in a 400 degree oven for about 10-15 minutes. Until the biscuits start turning golden brown.
Allow to cool for a few minutes before serving.
